Answer:
B. 2 + 6x and 2(3x + 1) Choose
D. 3x and 4(x + 1) – x – 4 Choose...
E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...
Step-by-step explanation:
A. 3x + 14 – x + 112 and 4x + 134 Choose...
3x + 14 - x + 112
= 2x + 126
And
4x + 134
Not equivalent
B. 2 + 6x and 2(3x + 1) Choose...
2 + 6x
And
2(3x + 1)
= 6x + 2
Yes, equivalent
C. 3(x + 1) – (1 + x) and 2x + 3 Choose...
3(x + 1) - (1 + x)
3x + 3 - 1 - x
2x + 2
And
2x + 3
No, not equivalent
D. 3x and 4(x + 1) – x – 4 Choose...
3x
And
4(x + 1) - x - 4
= 4x + 4 - x - 4
= 3x
Yes, equivalent
E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...
5.5 + 2.1x + 3.8x - 4.1
1.4 + 5.9x
And

First set up a propotion to figure out the actual measurement of the side of the table.
1.25/6.50 = 2.50/x
Cross multiply
1.25x =16.25
Divide both sides by 1.25
X= 13
Plug 13 into the Area of a square formula
A= side squared
A= 13^2
Area of the actual table top is 169 inches^2

To make x the subject of this equation, you need to set the equation equal to x. Or in other words, get the x variable all on its own on one side of the equation. To do this, simply add 5 to both sides of the equation.
The left hand side of the equation will be b+5
And the right hand side of the equation will be just x because -5+5=0 leaving just the x.
b+5=x or x=b+5
That is your answer.
