Is this the right answer? (have to use A= 1/2(b1+b2)h

Yes! It is 70 centimeters squared.

Step-by-step explanation:

did I not answer this question already lol?

1/2(base1+b2)(h)

1/2 (13+7)(7)

1/2 (20)(7)

1/2(140) = 70

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
