Answer: 23+9h+h^2
Step-by-step explanation:
f(3+h)=(3+h)^2+3(3+h)+5=
= 3^2+2*3*h+h^2+3*3+3*h+5=
= 9+6h+h^2+9+3h+5=
= 23+9h+h^2
Answer:
√17, √18,√19,√20,√21,√22,√23 ,√24
Step-by-step explanation:
Answer:
<4 and <8 are corresponding angle
Answer:
Step-by-step
The answer is 11 or 43.25
First, we subtract 15 yd² from the area given. Doing so, will give us an answer of,
x² + 8x
This expression can be factored out as (x + 8)(x). Thus, the dimensions of the flowed bed before its area is increased by 15 yd² are (x + 8) yd and (x) yd.
