6+x, when x = 3
6+(3)
6+3=9
Hello there!
Evaluate a² for a = -4
The first step we need to do is replace a by -4
So we have (-4)²
Now what you have realize is that we need to multiply -4 by itself twice.
So it should looks like this:
-4 * -4
The rules says that when we have minus * minus, the answer is positive.
So we have -4 * -4 = 16
Answer: 16
I hope this helps!

Answer:
Step-by-step explanation:
F(x)=(5 t^2+t )x to x+3
=5((x+3)^2-x^2)+(x+3-x)
=5(x^2+6x+9-x^2)+3
=5 (6x+9)+3
=30x+48
F'(x)=30
Answer:
15 R7
Step-by-step explanation:
<u> 015</u>
32/ 487
<u>0</u>
48
<u>32</u>
167
<u>160</u>
remainder 7
So you know that 30 + 30 + w + w = P. We also know the area is 240 square feet. Divide 240 by 30 to find the width of the area. 240 / 30 = 8. w = 8. So add 30 + 30 + 8 + 8 to find that P = 76. HOWEVER, remember that George is using part of his house as a wall instead of a fence. So subtract 8 from 76 to get 68 ft. George will need 68 ft. of fencing for his dog run.
