Answer:
A = 49 in^2
Step-by-step explanation:
The perimeter of a square is found by
P = 4s where s is the side length
28 = 4s
Divide each side by 4
28/4 = 4s/4
7 =s
We want to find the area
A = s^2 where s is the side length
A = 7^2
A = 7^2
A = 49 in^2
Answer:
C
Step-by-step explanation:
The number line in option C contains the points -4, -1, 1 and 2 correctly plotted.
Answer:
Step-by-step explanation:
x(3x+2)=16
3x²+2x-16=0
3x²+8x-6x-16=0
x(3x+8)-2(3x+8)=0
(3x+8)(x-2)=0
either 3x+8=0
x=-8/3(rejected as width can't be negative)
x-2=0
x=2
so width=2
length=3×2+2=6+2=8
