Answer :
[tex] \orange{ \boxed{ \pink{ {x}^{2} - 9}}}[/tex]
Step-by-step explanation :
We can use the formula that :
(a + b) (a - b) = a(a - b ) + b(a - b)
= a² - ab + ab - b² = a² - b²
_________________________
(x + 3) (x - 3)
We have :
a = x
b = 3
So :
( x + 3 ) ( x - 3 )
x (x - 3 ) + 3 (x - 3 )
x² - 3x + 3x - 9
x² - 9
Answer = x² - 9

Answer:
1.15
Step-by-step explanation:
Answer:
1.15
Step-by-step explanation:
So, first it would be helpful to change this from an improper fraction to a mixed number. Because we have an improper fraction now, we need to make this a mixed number by seeing how many times 23 can go into 20. Twenty-three can't go into 20, but if we take away 3 from 23 it can.
So, now we have 20/20 but with a remainder of 3/20. Because 20/20 = 1, it becomes a whole number of 1 and 3/20. Because there is a whole number of 1, we can put this as the whole number for the decimal. The fraction 3/20 is equal to the decimal 0.15, so we can now put the decimal together now that we have all the parts for the answer needed, which is 1.15.
I hope that this helps.

Sandy went to her local zoo that featured 34 tion exhibits. If the zoo features 40
exhibits in total, then what percent of the zoo's exhibits feature lions? Round your
answer to the nearest whole number if necessary.
Answer:
85%
-> If 34 of the 40 exhibits are lions, then 34/40 are lions.
-> 34/40 = 0.85
-> 0.85 * 100 = 85%

Two numbers whose product is 40 and sum is -22
Answer:
-2, -20
Step-by-step explanation:
x * y = 40 (1)
x + y = -22 (2)
Multiply by x on (2):
x^2 + xy = -22x
x^2 + 40 = -22x
x^2 + 22x + 40 = 0
(x + 2)(x + 20) = 0
x = -2, -20 (answer)

Determine the average rate of change of f (x) = x² - 10x + 5 over the interval [-4, 4].
=
-
Answer:
f ( x ) = ( x - 5 ) ² - 20
Step-by-step explanation:
1- Add the same value to both sides
f ( x ) = x ² - 10x + 5
2- Add 25 to the expression
f ( x ) + ? = x ² - 10x + ? + 5
3- Add 25 to the left-hand side
f ( x ) + ? = x ² - 10x + 25 + 5
4- Factor the expression
f ( x ) + 25 = x ² - 10x + 25 + 5
5- Move the constant to the right
f ( x ) + 25 = ( x - 5 ) ² + 5
6- Calculate
f ( x ) = ( x - 5) ² + 5 - 25

A can of soup weights 251 grams. How many cans
Would weigh about a kilograrn?
Answer:
0.251 kg
Step-by-step explanation:
To convert from grams to kilograms, we divide the # of grams by 1000, or move the decimal point to the right by 3.
[tex]25.1[/tex] [tex]2.51[/tex] [tex]0.251[/tex]Therefore, the answer is 0.251 kg.
Answer:
4 cans
Step-by-step explanation:
1kg = 1000g
=> 1000g/251g
= 3.9 cans which is around 4

Use < , > , = , ≤ , ≥ to complete these statements. 1) if x < y , then y___ x, 2) if x > 5 and 5 > y, then x ___ y, 3) if x is four at most, then x ___ 4, 4) if x - y = 0, then x ___ y Can someone please help me I've been stuck on these for 3 days.
Answer:
1) y > x
2) x > 5 > y
3) x ≤ 4 ( or 4 ≥ x )
4) x = y
Step-by-step explanation:
1) 1. y is greater than x
2. so y > x
2) 1. 5 is less than x and more than y
2. we can write this like x > 5 > y
3. you can just squish them together as a shortcut usually: x > 5 and 5 > y --> x > 5 > y
3) 1. x is for at most, we can say this as x is less than or equal to 4
2. this is written as x ≤ 4 or 4 ≥ x
4) 1. x - y = 0 so x and y must be the same value
2. therefore x = y
What is the value of x? □ ft. ( Will Mark Brainliest working on it now ).
Answer:
67.5 ftStep-by-step explanation:
Use the ratio of corresponding sides:
97.5/x = 71.5/(71.5 - 22)97.5/x = 71.5 / 49.5x = 97.5*49.5/71.5x = 67.5Please help: Determine the points at which the graph of the function has a horizontal tangent line.
