Answer:
x = 10
Step-by-step explanation:
First, to solve for x, you need to isolate the variable, meaning that it needs to be the only term on one side of the equation. To do this, we'll just cancel out the -3 by adding +3 on both sides of our equation.
x - 3 = 7
+3 +3
Leaving us with our answer, x = 10
Hope this helped :)
12 I believe
have a great dayy
happy summee
area=(b1+b2)*h all divided by 2
a=(12+12+8.7)*4.9 all divided by 2
a=32.7*4.9/2
a=160.23/2
a=80.12 sq. ft.
63.
That would be 63 because all the others are perfect squares. 63 is not a perfect square.
