What is the simplified expression for 6(2(y + x))

or

Step-by-step explanation:

We have:

We must begin to simplify from the innermost parenthesis of the expression, in this case we solve it by multiplying the elements of such parenthesis by the 2 outside.

And now we only have one parenthesis to eliminate, we do this by multiplying the elements of the parenthesis by 6:

which can also be expressed as:

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
