Given two parallel lines cut by a transversal, solve for x.

x=3

Step-by-step explanation:

make it equal 0 since 2x^2=4x+30

0=2x^2+4x+30 then you factor out the 2

2(x^2+2x+15) then you factor and get

2(x+5)(x-3)

So x=-5 or x=3 and x cannot be negative

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
