The area of the trapezoid is 70 square inches. What is the length of the larger base?

20

Step-by-step explanation:

Multiply 20 by 2 to get 40 and multiply 10 by 2 to get 20 and multiply 5 by 2 to get 10 then add all of the numbers you get from multiplying the previous #'s to get 70 square inches

20 i think srry if wrong

Step-by-step explanation:

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
