Answer: Option A: 14t + 4s
Step-by-step explanation:
To find the perimeter of a shape, add up all of its side lengths. We know that the length of the rectangle is (s + 2t), and its width measures (s + 5t).
To find the perimeter, multiply the width by 2 and the length by 2 and add those expressions:
P (perimeter) = 2(s + 2t) + 2(s+5t)
P = 2s + 4t + 2s + 10t
P = 4s + 14t or 14t + 4s
Hope this helps.
Is the box cube or a parallelogram?
Answer:
It's value is less than 0
Step-by-step explanation:
The vertex is when x=-b/2a
in this case, b=-8, a=-1, so x=-(-8)/2(-1)=-4
when x=-4, y=-(-4)²-8(-4)+2=18
so the answer is B.
