What is the area of this trapezoid?

Sonja [21]

Answer:

$\boxed{Area \: of \: trapezoid = 126 \: {in}^{2}}$

Given:

AB = 12 in.

DF = 2 in.

FE = 12 in.

EC = 2 in.

BE = 9 in.

Step-by-step explanation:

$Area \: of \: trapezoid = \frac{1}{2} (sum \: of \: parallel \: sides) \times height$

Parallel sides are:

AB = 12 in

DC = DF + FE + EC

= 2 + 12 + 2

= 16 in.

Height:

BE = 9 in.

$Area \: of \: trapezoid = \frac{1}{2}(12 + 16) \times 9 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1}{2 } \times 28 \times 9 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 14 \times 9 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 126 \: {in}^{2}$

What is the volume of this stack of blocks if each block measures 1 centimeter on each side ?

zlopas [31]

The volume of a cube is just cubing one side (1 times one times 1). So you just count up the cubes I guess!

(URGENT!!!! WILL MAKE BRAINLIEST) Write a quadratic equation with -4 and 3/2 as its roots. Write the equation in the form ax² +

LekaFEV [45]

Answer:

2X^2+5/2X-3/2=0

Step-by-step explanation:

To identify the equation use the following method

(X-a)(X-b)=0

Put values

a=-4

b=3/2

(X+4)(X-3/2)=0

X^2+4X-3/2X-3/2=0

X^2+(8X-3X)/2-3/2=0

X^2+5/2X-3/2=0
