lara [203]3 years ago
8 0

Answer:

Step-by-step explanation:

Perimeter of triangle =  4x - 3 + x + 9 + 8

                                   = <u>4x + x</u> -<u> 3 + 9 + 8</u>

                                  = 5x + 14

Area  = \frac{1}{2}*base *height

         = \dfrac{1}{2}*8*3x\\\\= 4 * 3x\\\\= 12x

What’s -2y+16=10 plz solve 2 step equation
konstantin123 [22]

Answer:

y=3

Step-by-step explanation:

To solve this 2 step equation, we need to get y alone. Lets write out the equation

-2y+16=10

Subtract 16 from both sides

-2y-16+16=10-16

Subtract

-2y=-6

divide both sides by -2

-2y/-2=-6/-2

divide

y=3
