Tim = 12
Jack 1st = 12 - (12 x 0.30)
second year
Jim = 1 + x
Jack = x
12 - (12 x 0.30) =
12 - 3.6 = 8.4
Jack = $8.4 per hour
Tim = 8.4 + 1
Tim = $9.4 per hour
The width of the mat around the photo is 3 inches
The combined area of the of the photo and math = 224 square inches
The combined area is represented as:
(2w +8)(2w + 10) = 224
Expand the equation using the distributive rule
Divide through by 4
Factorize the resulting quadratic equation to solve for w
w - 3 = 0
w = 3
w + 12 = 0
w = -12

Answer:
28
Step-by-step explanation:
Think of the shape being made up of a square on top that is 4 units by 4 units and a trapezoid on the bottom with bases 4 and 2 and height 4.
area = area of rectangle + area of trapezoid
area = LW + (b1 + b2)h/2
area = 4 * 4 + (4 + 2)(4)/2
area = 16 + 12
area = 28
Answer:
Part A:
The area of a square is (16a2 − 24a + 9).
16a2 − 24a + 9
= (4a)^2 - 2 x 4a x 3 + 3^2
= (4a - 3)^2
=> Side of square: 4a - 3 (if a > 4/3) or 3 - 4a (if a < 4/3)
Part B:
The area of a rectangle is (9a2 − 25b2).
9a2 − 25b2
= (3a)^2 - (5b)^2
= (3a - 5b)(3a + 5b)
=> Side of rectangle: 3a - 5b and 3b + 5b
