The 2 in the middle is the one that i needed

The equation is p=34a+12, and a=7

Step-by-step explanation:

Perimeter is all of the sides added together

p=12a+6a+8+6a+8+10a-4

Combine like-terms

p=34a+12

Solve for a by making p equal to 250

250=34a+12

Subtract 12 from both sides

238=34a

Divide both sides by 34

7=a

answer:

3x-6

step-by-step explanation:

less than means subtract ao u subtract the 3x nd the 6.less than is also a turn around phrase.so the 6 would go in the back and the 3 nd the variable would go to the front and product means to multiply.if u multiply a # nd a variable you dont need to put the multiplication sign.just put it next to each other
