As per cubic equation, there will be one real solution of the given equation.
What is a cubic equation?"A cubic equation is an algebraic equation of degree three and is of the form ax³ + bx² + cx + d = 0. x is a variable.
Here a, b and c are the coefficients and d is the constant"
Given cubic equation is:
x³ + 6x² + 12x + 8 = 0
⇒ x²(x + 2) +4x(x + 2) + 4(x + 2) = 0
⇒ (x + 2)(x² + 4x + 4) = 0
⇒ (x + 2)(x + 2)² = 0
⇒ (x + 2)³ = 0
⇒ x = -2
There will be one real solution of the given equation.

A kitchen sink faucet streams 0.5 gallon of water in 10 seconds. A bathroom sink faucet streams 0.75 gallon of water in 18 seconds. Which faucet will fill a 3-gallon container faster?
Answer:
A kitchen sink faucet
Step-by-step explanation:
0.5 gallon of water × 6 = 3 gallons
10 second × 6 = 60 seconds = 1 minute
0.75 gallon of water × 4 = 3 gallons
18 seconds × 4 = 72 seconds = 1 minute 12 seconds
1 minute is faster than 1 minute and 12 seconds by 12 seconds
so a kitchen sink faucet

you multiply $2.90 by 2 because the muffins are 2.90 for 6 muffins so if you add 6 on it would be a dozen so all you have to do it multiply 2.90 by 2 please tell me if this is correct or wrong if it is wrong i will change it to the correct answer thank you
Which sequence could be partially defined by the recursive f (n + 1) = f(n) + 2.5 for n > 1?
Answer:
Step-by-step explanation:
f(n + 1) = f(n) + 2.5
f(1) = -10
f(2) = f(1) + 2.5 = -10 + 2.5 = -7.5
f(3) = f(2) + 2.5 = -7.5 + 2.5 = -5
f(4) = f(3) + 2.5 = -5 + 2.5 = -2.5

Louis owns a rectangular piece of property with an area of 1 3 4 square miles. The length of the property is 2 1 3 miles. What is the width of the property?
Answer:
Step-by-step explanation:
Area of the land A - Length * Width
Given
A = 1 3/4 mi²
Length L = 2 1/3 miles
Required
Width of the property
Substitute into the formula;
A = LW
W = A/L
W = 1 3/4/(2 1/3)
W = 7/4 ÷ 7/3
W = 7/4 × 3/7
W = 3/4 miles
Hence the width of the property is 3/4 miles
Hannah purchased three items at the store for $7.05, $8.12, and $3.97. She paid for
her items with a $50 bill. Which most closely estimates the change Hannah should
receive?
Answer:
She should receive $30.86
Step-by-step explanation:
$7.05 + $8.12 + $3.97 =19.14
50 - 19.14 = 30.86
Using the subtraction method we have found that Hannah will receive the change of $30.86
What is subtraction?Subtraction is an arithmetic operation that represents the operation of removing objects from a collection
Total cost of three items =7.05 + 8.12 + 3.97 =$19.14
She paid $50 bill
Change that Hannah should receive is =50 - 19.14 = $30.86
Hence, change that Hannah should receive is$30.86

Is 56 × 19/20 greater than or less than 56?
Answer:
Less
Step-by-step explanation:
56 is multiplied by 19/20 which is obviously less than one
Answer:
Step-by-step explanation:
56/60 = 0.9333
19/20 = 0.95
Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.9333 is NOT greater than 0.95 which also means that 56/60 is NOT greater than 19/20.
Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!
Let R be a region in the xyâplane and β >0 be a constant. What is the region R that will minimize the value ofintegral(x^2 + y^2 - b^2)?
Let R be region in the xy-plane and β>0 be the constant. What is the region R that will minimize the value of integral (x² + y² - β²).
i.e.
[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex]
Answer:
0
Step-by-step explanation:
Given that:
[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex]
where;
R is the region in the xy-plane.
To minimize our double integral, we have to determine the region over which the function we are integrating has a negative value.
x² + y² - β² ≤ 0 ; where β > 0 is a constant
x² + y² ≤ β² is the circle with center (0,0)
Radius "β" because R: x² + y² ≤ β²
The polar coordinates: x = rcosθ and y = rsinθ
x² + y² = r²
⇒ r limits : r = 0 → β
⇒ θ limits : r = 0 → 2π
[tex]\iint_R(x^2+y^2-\beta^2) \ dA =\int\limits ^{2 \pi}_{\theta=0} \int \limits ^{\beta}_{r=0}( \beta^2 -\beta^2) \ rd \ rd\ \theta[/tex]
[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex] = 0

I think they are asking the area of the triangle so we are going with that.
Step-by-step explanation:
Easiest way to do this is find the area of the incomplete square, and then cut that in half for the triangle.
so it is 4 cm wide
and 8 cm tall
length x width = area
8 x 4 = 32
32/2 = 16
So your answer should be 16 cm
