Answer:
Hence the expression
.
Step-by-step explanation:
- The given expression is (x+8)(x+3).
- We have to multiply the given expression.
- Multiply the (x+8) by 3 , multiply the (x+8) by x then add like terms.

Answer:
Center (-13,11) , radius 3
Step-by-step explanation:
The given circle has equation

We compare this to the general equation.

where (-a,-b) is the center.
This implies that;
2a=26

2b=-22
b=-11
The center is therefore (-13,11)
The radius is given by



The radius is 3
<u>Answer</u>
The first student was right.
The length of the long side is at least 13 inches.
<u>Explanation</u>
The perimeter of any figure is the distance all round.
Perimeter of a rectangle = 2(l+w). Where l is length and w is the width.
2(l + w) ≥ 30
2{(x-3) + 2} ≥ 30
2(x-3+2) = 30
2(x - 1) ≥ 30
x - 1 ≥ 15
x ≥ 16
When x = 16,
l = 16-3
= 13 inches
The length of the long side is 13 inches. The first student was right.
