Answer: length = 13
Width = 22
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length × width)
The length of the rectangle is represented by (x+3) and the width is represented by (3x-8). If the perimeter of a rectangle is 70, it means that
2[(3x - 8) + (x + 3)] = 70
Dividing both sides of the equation by 2, it becomes
3x - 8 + x + 3 = 35
3x + x - 8 + 3 = 35
4x - 5 = 35
4x = 35 + 5 = 40
x = 40/4
x = 10
Length = x + 3 = 10 + 3
Length = 13
Width = 3x - 8 = 3 × 10 - 8
Width = 22
Answer:
Step-by-step explanation:
3/4- 1/28
3(7)/4(7)= 21/28-1/28
=20/28
=5/4
Answer:
2x + 14
Step-by-step explanation:
To evaluate h(x + 5) substitute x = x + 5 into h(x), that is
h(x + 5) = 2(x + 5) + 4 = 2x + 10 + 4 = 2x + 14
