The lengths of the bases of a trapezoid are 17 inches and 10 inches. The trapezoid has an area of 189 square inches.
Mamont248 [21]

Answer:

height of this trapezoid is 14 inches.

Step-by-step explanation:

\boxed{Area -of -trapezoid=\frac{a+b}{2} h}

[ Here lengths, a = 17 and b = 10 and area of trapezium given 189 ]

using the formula:

\frac{17+10}{2} *h = 189

\frac{27}{2} h = 189

h = \frac{189*2}{27}

h  =14

A frame is 6in tall and 8 in wide. What if it was reduced to a width of 4in then how tall will it be
kkurt [141]

Answer:

  3 in

Step-by-step explanation:

Apparently, we are to assume that the height and width are proportional:

  height/width = (6 in)/(8 in) = (new height)/(4 in)

Multiplying by 4 in will tell us the new height:

  new height = (4 in)(6/8) = 3 in

The reduced frame will be 3 inches tall.

Can someone help me!!!!!!!!!!!!

KU and UM are equal to each other.
KU = 3x + 3
UM = 4x - 4
3x + 3 = 4x - 4
3x = 4x - 7
-x = -7
x = 7

If you plug that into either one of the equations, you get 24.
3(7) + 3
24

So depending on your question, x is 7, KU is 24, and UM is 24.
