I need help with my math

42

Step-by-step explanation:

If you add 42+42+24+24= 132. If they are similar, then the other shape should be equal. So, 35+35+10+10= 90. Then you subtract 132-90= 42. So 42 is the missing amount that needs to be added to x.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!
