Answer:8
Step-by-step explanation:
X+56=x^2
X^2-x-56=0
X^2-8x+7x-56=0
X(x-8)+7(x-8)=0
(X+7)(x-8)=0
X+7=0 or x-8=0
X=-7 or x=8
Answer:

I counted all the squares
The answer you're looking for is A: 3
5x-1=14
+1 +1
(the -1 cancels out)

Answer:
16022 square foot
Step-by-step explanation:
The world's largest cookie was baked in North Carolina in 2003. Its diameter was 100 feet and it contained about 6,000 pounds of chocolate chips! If the cookie was a cylinder 1 foot tall, and you wanted to cover it with icing, how many square inches would you have to ice? Use 3.14 for .
We find the surface area of the cylinder
= 2πr(r + h)
r = Diameter /2 = 100 feet/2
r = 50 feet
h = 1 feet
Hence
2 × 3.14 × 50(50 + 1)
= 16022.122533 square foot
= 16022 square foot
