Answer:
9 inches each side
Step-by-step explanation:
Answer:
D. x = -5/2, x = -1/2
Step-by-step explanation:
2x² + 7x + 5 = 0
(2x + 5)(x + 1) = 0
2x + 5 = 0 or x + 1 = 0
2x = -5 or x = -1
x = -5/2 or x = -1/2
Let L = length, W = width, and formula for perimeter (each side added) is
P = 2L + 2W
The first statement tells us L = 3W so we can substitute 3W for L in the formula.
P = 2(3W) + 2W
The 2nd statement tells us to make the expression for the perimeter into an inequality where it is ≥ (greater than or equal to) 104
2(3W) + 2W ≥ 104
We only need to solve this to find the possible values for W/
2(3W) + 2W ≥ 104
8W ≥ 104 ← result of simplifying left side
W ≥ 13 ← result of dividing both sides by 8
ANSWER: The width is greater than or equal to 13: W ≥ 13
Answer:
360 meters
Step-by-step explanation:
= 90
one edge = 90 meters
90 x 4 = 360
360 meters
