(3x^2 - 2x)(x + 4)
<em><u>First step would be: distributive property.</u></em>
3x^3 + 12x^2 - 2x^2 - 8x
<em><u>Combine like terms.</u></em>
3x^3 + 10x^2 - 8x is the simplified form of the functions multiplied.
Your answer is D.
Answer:
Short leg = 24inches
Long leg = 32inches
Hypotenuse = 40inches
Step-by-step explanation:
Given:
- shorter leg is 8inches shorter than the longer leg
- hypotenuse is 8inches longer than the longer leg
- longer leg = x inches
<u>Pythagorean Theorem:</u>
a²+b²=c² → (x-8)²+ x² = (x+8)²
Solving for both sides:
x² - 16x+ 64 + x² = x²+ 16x + 64
<u>More Painful Solving:</u>
x² - 32x = 0
x(x-32) = 0
x=0 or 32
Can't use the 0 so we trash it!
x=32
add 8 to get the hypotenuse and subtract 8 to get the short leg
Answer:
a=-16, b=11, c=23
Step-by-step explanation:
The function that represents the table is
We substitute x=-5 to find the value of a.
We evaluate to obtain:
To find the value of b, we substitute x=4,
We get:
To find c, we plug in x=8,
C. Y=12
There’s no x variable
