Answer:
b = 7
Step-by-step explanation:
108 = -2(-5 - 7b)
Distribute -2 to the terms inside the parenthesis:
108 = 10 + 14b
Subtract 10 from both sides of the equation to isolate 14b:
108 - 10 = 10 + 14b - 10
98 = 14b
Divide 14 on both sides of the equation to solve for b:
7 = b

For this case the area is given by:
A = (22 + x) * (28 + x) = 722
Rewriting we have:
616 + 22x + 28x + x ^ 2 = 722
x ^ 2 + 50x + 616 - 722 = 0
x ^ 2 + 50x - 106 = 0
Solving the polynomial we have:
x1 = 2.04
x2 = -52.04
We take the positive root:
x = 2.04 inches:
Answer:
The width of the border to the nearest inch is:
x = 2inches
Answer:
a=216
Step-by-step explanation:
The lateral surface area of the cylinder = 80 sq cm.
Step-by-step explanation:
Given,
The circumference of the base of the cylinder is 16 cm
So, 2 X pi X r = 16 cm ( where r be the radius of the base)
Now, the lateral surface of the cylinder = 2 X pi X r X H ( where H be the height = 5 cm)
= 16 X 5 sq cm
= 80 sq cm
Hope it helps you.
