1. (The base on top is 15 ft.
To find the base on the bottom you have to first find the length of the right side of the triangle. 7 - 4 = 3. Then, square both sides of the triangle and add them together. 15^2 + 3^2 = 234
Next take 234 and find its square root = 15.3. The bases of the trapezoid are 15 and 15.3)
2. (Both bases and the height.)
3. (2l + 2w does not belong, all of the equations are formulas for area but that one is perimeter)
You will have to use trial and error in order to find the values for x and y.
Just keep plugging values until you get 7.
I found x is equal to 2 and y is equal to 5.
3(2) + (1/5)5 = 7
6 + 5/5 = 7
6 + 1 = 7
7 = 7
An equilateral triangle have 3 congruent sides.
Divide the total (15x +3) by 3
(15x + 3)/3 = 5x + 1
Each side's length is 5x + 1
hope this helps
It’s B because the domain(x) doesn’t repeat like the other options.
Answer:
x = - 8, y = 2
