Answer:

√[ (a + b)^2 + c^2 ].

Step-by-step explanation:

They are both equal in length because we have an isosceles trapezoid here. We see form the drawing it is symmetrical about the y axis.

The diagonal = the line joining points (b, c) and (-a, 0)

= √[ (b - -a)^2 + (c - 0)^2 ]

= √[ (a + b)^2 + c^2].

QUESTION 7 Solve for x. (3x + 32) (5x-8) O a. 3 b. 12 O c. 20 O d. 19.5

Alchen [17]

Answer:

The answer is x = 20

Step-by-step explanation:

If you set both equations equal to each other and solve for x, you will get 20.

3x+32 = 5x-8 add 8 to both sides

3x+40 = 5x subtract 3x from both sides

40 = 2x divide by 2 on both sides

20 = x
