Answer:
x²+8x+16
Step-by-step explanation:
f(x) = (x+4)²
= (x+4)(x+4)
= x² + 4x + 4x + 16
= x² + 8x + 16
Answer: 10
Step-by-step explanation:
This is because if it was 9, then 9^2 would be 81 and 10^2 would be 100. 81 is 11 numbers a way from 92, while 100 is 8 numbers from 92, making 10 the <u>closest</u> estimate.
The answer would be "114.2"
5+1/7x=-2
-5 -5
1/7x= -7
X= -49
