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.

Answer:
p < -9
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define inequality</u>
4p - 1 < 3p - 10
<u>Step 2: Solve for </u><em><u>p</u></em>
- Subtract 3p on both sides: p - 1 < -10
- Add 1 on both sides: p < -9
Here we see that any number <em>p</em> less than -9 would work as a solution to the inequality.
7/8 is greater that 3/10
because,
7/8 = 35/40
and
3/10 - 12/40
So which is greater? its 7/8
