With 11 and 12 due tomorrow alos explain how u got the answer

11. X=7

For 12, im not sure but I think it's

Step-by-step explanation:so for 11 I just divided 70 by 10 cuz to find the area of a rectangle or square you multiply the width by length. For 12 I think it's 5 because I know that you multiply the width by length then divide it in half.

Also what grade are you in?

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
