Answer: x=2, y=7

Step-by-step explanation:

6x+3y=33.................. (1)

4x+y=15.......................(2)

Using elimination method multiply equation one by 1 and equation 2 by 3

6x+3y=33...................(3)

12x+3y=45....................(4)

Eliminating y

We have

6x+3y=33

-

12x+3y=45

The single equation becomes

-6x+0=-12

-6x=-12

Minus cancelled minus

6x=12

x=12/6

x=2

To find y substitute x=2 in equation 1

6x+3y=33

6(2)+3y=33

12+3y=33

3y=33-12

3y=21

y= 21/3

y=7

Answer this plz!!!!!!!!!!
belka [17]

That's a trapezoid,

A = \frac 1 2 (b+B)h

A = \frac 1 2 (4+12) 4 = 32

Answer: 32

But say we didn't know the formula. We can chop out the 4 by 4 square and we have two 45/45/90 triangles side 4 left over, so two 4 by 4 squares,

A = 2(4)(4) = 32

We can think of this as 12 by 4 rectangle with two 4 by 4 right triangles chopped out:

A = 12(4) - 2(1/2)(4)(4) = 48 - 16 = 32
