Answer:
B.) 4x^2 - 15x - 54
Step-by-step explanation:
You want the product f(x)·g(x) when f(x) = 4x+9 and g(x) = x-6.
Binomial multiplicationThe distributive property can be used to find the product. Each term of one binomial is multiplied by every term of the other, and like terms are combined.
f(x)·g(x) = (4x +9)·(x -6)
= 4x(x -6) +9(x -6)
= 4x² -24x +9x -54 = 4x² +(-24 +9)x -54
f(x)·g(x) = 4x² -15x -54 . . . . . . . . . . matches choice B
__
Additional comment
The product of two binomials is sometimes described using the mnemonic FOIL, for First, Outer, Inner, Last. These refer to the locations of the terms involved in the four products
(4x +9)·(x -6) — First(4x +9)·(x -6) — Outer(4x +9)·(x -6) — Inner(4x +9)·(x -6) — LastThese products are the same as the ones we show above.
The FOIL mnemonic is only helpful for two binomials. Any polynomials can be multiplied using the distributive property.

Which of the following is a multiple of 2 and 4?
The multiple of 2 and 4 is 48.
A number that is the result of a given number and another natural number is called a multiple of that number. To find the multiple of a number, multiply the number by any whole number.
The given options are A. 50, B. 58, C. 54, and D.48.
The multiples of 50 can be written as,
[tex]50=2\times5\times5[/tex]
The multiples of 58 can be written as,

An equation to describe the relationship between g, the number of gems, and c, the number of chests is; g = 300c
How to solve Linear Equation Word Problems?
In adventure A, when number of gems is 600, we see that number of chests is 2. Thus;
Rate of gems per chests = 600/2 = 300 g/c
In adventure B, when number of gems is 1500, we see that number of chests is 5. Thus;
Rate of gems per chests = 1500/5 = 300 g/c
In adventure C, when number of gems is 4800, we see that number of chests is 16. Thus;
Rate of gems per chests = 4800/16 = 300 g/c

show that the convergence of a series is not affected by changing a finite number of its terms. (of course, the value of the sum may be changed.)
Convergent Series:
A Convergent Series is a series whose partial sums tend to a specific member is called a limit.
∑ 1/2n = 1/2+ 1/4 + 1/8 + 1/16 +........
Given an infinite series ∑₁ ∞ an determine the series is convergence. Recall that we can actually do better with geometric series not only we can determine convergence but also divergence. We can also calculate geometric series.
Suppose we are given a series ∑ aₙ which is not quite a geometric series but becomes a geometric series for sufficiently large n. That is we can find an integer N such that aₙ = aₓⁿ for all n > N. we don't have a general formula for aₙ when n ≤ N. The values of aₙ for small n don't effect Sₙ is convergence or not.
As a moment of fact, we never used the fact that aₙ eventually become geometric. More general ∑aₙ is convergent series, we can add a finite number of terms to the be gaining of this series or remove a finite number of terms from the be gaining of the series without affecting the convergence of the series. For Example: if ∑aₙ convergence then so does
10 + 10¹⁰ + 10 ¹⁰⁰ + 10¹⁰⁰⁰ + ∑aₙ
Similarly, if ∑aₙ convergence then,
a₁₀₀₀ +a₁₀₀₁ +a₁₀₀₂ + ..... = ∑₁₀₀₀ ∞ aₙ
However, the fact that we are only adding finitely many terms to the series is essential. That is, when it comes to determining convergence of a series ∑aₙ , we can see that only the asymptotic behavior of ∑aₙ matter, that is, only the behavior of the sequence aₙ as n--- ∞ affects convergence.

You buy a basket of 24 strawberries. You eat them as you walk to the beach. It takes the same amount of time to walk each block. When you are halfway there, half of the berries are gone. After walking 3 more blocks, you still have 5 blocks to go. You reach the beach 28 minutes after you began. One-sixth of your strawberries are left.
You walked _
blocks in 28 minutes. At this rate you walk 1 block in

You walked 16 blocks in a time of 28 minutes. At this rate you walk 1 block in 1 minute 75 seconds.
What is distance?In Science, distance can be defined as the amount of ground that is covered (travelled) by a physical object over a particular period of time and speed, irrespective of its direction, starting point or ending point.
Mathematically, the distance traveled by a physical object (body) can be calculated by using this formula:
Distance = speed (rate) × time
Note: Let the variable x represent the halfway distance.
Since it takes the same amount of time to walk each block and halfway there, half of the berries are gone. Therefore, we have the following:
At point x, the number of strawberries that is left is equal to 12 strawberries while the distance after walking 3 more blocks, you still have 5 blocks to go would be given by:
1/2 × x = (3 + 5) = 8
1/2 × x = 8
Distance, x = 8 × 2
Distance, x = 16 blocks.
Now, we can determine the rate at which this person walks a block:
Rate (speed) = 28/16
Rate (speed) = 1.75 minutes.

What are the lengths of the major and minor axes of the ellipse?
(x−3)227+(y+4)245=1
The lengths of the major and minor axis are 4√6 and 4√3.
What is Major and Minor Axis?A point on a curve is described by an ellipse if its location is such that the sum of the distances between its two focal points is a constant.
(x−h)²/ b² +(y- k)² /a² = 1
Given:
(x−3)²/ 27+(y+4)² /45=1
The above equation can be compared to the standard equation of an ellipse
(x−h)²/ b² +(y- k)² /a² = 1
where, (h, k) = coordinates of the center of the ellipse
a = length of the semi major axis
b = length of the semi minor axis
By comparison, we have;
(h, k) = (3, -4)
a = √(24) = 2 x√6
b = √(12) = 2 x√3
and, length of the major axis = 2a
length of the minor axis = 2b
Thus, The length of the major axis is
2x a = 2 × 2 x √6 = 4√6

for the first 11 months of this year , Dan's sales averaged 24,870 a month. What must be Dan's sales for the next month if he wants his monthly average for the year to be 25,000
Dan's sales for the next month if he wants his monthly average for the year to be 25,000 is 36430.
How to calculate the value?Since for the first 11 months of this year , Dan's sales averaged 24,870 a month. The total amount will be:
= 11 × 24870
= 273570
Since Dan's sales for the next month if he wants his monthly average for the year to be 25,000, the amount will be:
= 12 × 25000
= 300000

The price of 72 rolls of toilet rolls in each shop is:

The time elapsed, to the nearest minute, until only 2 grams of the element remains is 15 minutes.
We have an element. The element has a mass of 400 grams. The element decays by 29.8% per minute. We need to find the time duration after which there will be only 2 grams of the element remaining. Let the initial mass of the element, the final mass of the element, the rate of decay, and the time elapsed be represented by the variables m, M, r, and t. We can write the equation as given below.
M = m(1 - r)^t
2 = 400(1 - 0.298)^t
0.005 = (0.702)^t
log(0.005) = t*log(0.702)
