Answer:
A = (x + 7)(x + 9)
Step-by-step explanation:
Let the width w = x
then length l = w + 4 = x + 4
Area = length x width
= x(x+4)
Then the the width is increased by 7 units and the length increased by 5 units.
w = x + 7
l = (x + 4) + 5 =x + 9
A = (x + 7)(x + 9)

Step-by-step explanation:
you can create other solutions by taking both 2 and 3 consecitvly and adding them until you get 28.
Answer:
x = 118
Step-by-step explanation:
1. All the angles in a pentagon add up to 540, so to find the value of x, we can use this equation x + 122 + 103 + 98 + 99 = 540.
2. (Solving)
Step One: Simplify both sides of the equation by adding like terms.
- (x) + (122 + 103 + 98 + 99) = 540
- x + 422 = 540
Step Two: Subtract 422 from both sides.
- x + 422 - 422 = 540 - 422
- x = 18
