A trapezoid has an area of 24 square meters. The lengths of the bases of the trapezoid are 5 meters and 7 meters. What is the height of the trapezoid?4 meters
144 meters
2 meters
1 meter

Answers

Answer 1
Answer: Write it as an algebraic expression

24m^2 = (5m + 7m)/2 x h
24m^2 = 12m/2 x h
24m^2 = 6m x h

Divide both sides of the equation by 6m

24m^2 / 6m = 6m/6m x h
4m = h

The height is 4m

-k - 17 = -5 - K - 12

Answers

Answer:

∴ K = 0

Step-by-step explanation:

- K -17 = -5 - K -12

- K + K = - 5 - 12 + 17

0 K = -5 + 5

0 K = 0

∴ K = 0

Answer:

All real numbers are solutions.

Step-by-step explanation:

−k−17=−5−k−12

−k+−17=−5+−k+−12

−k−17=(−k)+(−5+−12)

−k−17=−k+−17

−k−17=−k−17

−k−17+k=−k−17+k

−17=−17

−17+17=−17+17

0=0

Three vertices of a rectangle have coordinates (–3, 1), (7,1), and (7, –4). What are the coordinates of the fourth vertex of the rectangle?

A.
(–3, –4)

B.
(–3, –1)

C.
(7, –3)

D.
(7, 4)

Answers

The answer is A because a rectangle has sides that go straight down basically -3 there has to be two -3 for x coordinate and two 7 for y coordinate and the missing coordinate also has to line up with the coordinate right next to it so it must have -4 as it's coordinate so basically the coordinate vertically across from it has the same x coordinate and the coordinate horizontal from it has the same y coordinate. So it's (-3,-4)
