Answer:
<em><u>0=x</u></em>
Step-by-step explanation:
First you need to get the variable on one side of the equation
7-x+3=9x+10
+x +x
7+3=10x+10
Now we can combine like terms on the left side of the equation
10=10x+10
Subtract 10 from each side
10=10x+10
-10 -10
0=10x
Divide by 10
0 =10x
/10 /10
<em><u>0=x</u></em>
The frame will go around all 4 sides of the painting. That means that the length of each side of the painting will increase by 2.5 inches. The height, <em>h</em>, will now be <em>h</em> + 5 (2.5 inches on the top and the bottom). The width, 2<em>h</em> + 3, will now be 2<em>h</em> + 3 + 5 (again, 2.5 inches on the top and the bottom). The area would be given by
(<em>h</em> + 5)(2<em>h</em> + 3 + 5) = (<em>h</em> + 5)(2<em>h</em> + 8)
Multiplying this, we have:
<em>h</em>*2<em>h</em> + <em /><em>h</em>*8 + <em />5*2<em>h</em> + 5*8 = 2<em>h</em>² + 8<em>h</em> + 10<em>h</em> + 40 = 2<em>h</em>² + 18<em>h</em>² + 40
Answer:
