B. -3 combine like terms first then solve the equation normally
So you would have to set up a equation to find the length and width. The equation would be w+(w+2)=16
that simplifies to 2w+2=16
2w=14
w=7
the width is 7
the length is 9
1.Combine multiplied terms into a single fraction
2. Multiply by 1
3. Subtract 6 from both sides of the equation
4.Simplify
5.Subtract 3x from both sides of the equation
6.Simplify
7.Multiply all terms by the same value to eliminate fraction denominators
8.Simplify
9.Divide both sides of the equation by the same term
10.Simplify
Solution:x=4
<DOC = <AOB
= 91 degrees
<AOD = 180 - <AOB
= 180 - 91
= 89
Column A Column B
<AOD <DOC
89 91
Assuming the missing signs are pluses, that would work out to a^3 + 12a^2 + 14a + 5
