Answer:
The length of the rectangle is 159923.5 and the width of 53289.5
Step-by-step explanation:
We will make 2 equations one that is the perimeter and another that is the length with respect to the width
b = w*3+55
2b + 2 w = 426426
we will replace b with (w * 3 + 55) in the second equation
2b + 2 w = 426426
2(w*3+55) + 2w = 426426
we clear w to find its value
6w + 110 + 2w = 426426
8w = 426426 - 110
8w = 426316
w = 426316/8
w = 53289.5
Now that we have the value of w we replace it in the first equation and solve to find b
b = w*3 + 55
b = 53289.5*3 + 55
b = 159868.5 + 55
b = 159923.5
The answer is A.
I used the formula for finding the vertex of a parabola and I got the first answer choice. So A is correct. :)
Answer:
D
Step-by-step explanation:
Distribute:
3x-3 ≤ -18
Add 3 to both sides:
3x-3+3≤ -18+3
Simplify:
3x≤ -15
Divide both sides by 3:
x≤ -5
