Would be the value of x
gladu [14]

Answer:

for the perimeter to be made into a equation it would take the equation

2(3x - 5) + 2(2x + 1)

And for the perimeter to equal 42 x would have to equal 5

Step-by-step explanation:

so first of all we have to find our equation to equal 42:

2(3x - 5) + 2(2x + 1) = 42

you then multiply 2 for both parentheses:

(3x * 2) + (-5 * 2) + (2x * 2) + (1 * 2) = 42

so its now:

6x -10 + 4x + 2 = 42

now your going to add variables to variables and numbers to numbers:

(6x + 4x) + ( -10 + 2) = 42

to get:

10x + (-8) = 42

Now your going to add 8 to both sides:

10x + (-8) = 42

         +8    +8

Giving the equation:

10x = 50

now you divide both sides by 10 to get:

10x/ 10 = 50/10

x = 5

to solve you put 5 in place of the variable x:

2(3*5 - 5) + 2(2*5 + 1)

2(15 - 5) + 2(10 + 1)

20 + 22 = 42

So x equals 5 if the perimeter equaled 42

Step-by-step explanation:

This is because if you plug in the number 15 and 5 you would get 5=r15
