Hay sorry I forgot the picture last time but can some one help

Marina's design uses more cardboard.

in Kristen's design, it uses:

3*4/2*2+10*5+3*10+4*10=132 sq inches.

in Marina's design, it uses:

6*3*2+3*7*2+7*6*2=162 sq inches.

132<162

Therefore Marina's design uses more cardboard.

The difference between 2 designs are:

162-132

=30 sq inches

2? if not the correct answer you might need to provide more information

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
