Answer:
Step-by-step explanation:
Let L represent the length of the triangle.
Let W represent the width of the triangle.
The length of a rectangle is four more than three times the width. This means that
L = 3W + 4
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
If the perimeter of this rectangle is at least 70 square centimeters, an inequality that can be solved to find the width of the rectangle is
2(L + W) ≥ 70
L + W ≥ 70/2
L + W ≥ 35
Answer:
222
Step-by-step explanation:
1995 is 5 years after 1990,
So x = 5
y = -2.5x² + 27.5x + 147
Find y when x = 5
y = -2.5(5²) + 27.5(5) + 147
y = 222
