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)
Ok so first u would add 3+1 which gives u 4 and then add 1/4 which should give u 4 1/4
To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.
