Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170
And that is the answer.
Do you have a picture where I can understand it much better?

Answer:
-10
Step-by-step explanation:
2+8 just add the negative sign
or
-8 minus 2
The answer would be 11/2.
2d = 5 + 6 (add 6 to both sides)
2d = 11 (simplify 5 + 6 to 11)
d = 11/2 (divide both sides by 2)
Decimal form is 5.5.
