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
The answer is c because if you do the math it’s 15/2
Answer:
You need to satisfy the equation.
I will solve one.
Step-by-step explanation:
x -2 < -5
now add + 2 to both sides to keep its value.
now we end up with x <-3, which means that the value of x should be less than -3 in order to satisfy the equation.
So -5 is an answer, -4 is an answer, but not -3 because it should be less than -3 not equal.
As for number 9 the dash underneath the less than symbol means that it can equal to.
Hope this helps.

Answer:
x is 13.03
Step-by-step explanation:
Start by determining the length of the horizontal side of one of the triangles shown. The Pythagorean Theorem applies here:
(horizontal side)² + 17² = 19², so that:
(horizontal side)² + 17² = 19² - 17², or 72
Then the length of the horizontal side is +√72, or √36√2, or 6√2.
From the diagram it is obvious that the width of the rectangle, x, can be found by subtracting twice the length of the horizontal side of one of the triangles from 31 (base of the entire figure):
x = 31 - 2(6√2) = 13.03
x is 13.03
