Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than 120.

Answer:
Inequality : 4x+8 < 120
x<28
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a rectangle (P)= 2 length +2 width
Where:
Width = x
Length = x+4
Replacing with the values given
P = 2 (x+4) + 2x
P = 2x+8+2x
P=4x+8
Since the perimeter of the rectangle must be less than 120:
4x+8 < 120
Solving for x
4x<120-8
4x<112
x<112/4
x<28

Answer:
My own answer to your question is x=10
Answer:
-3
Step-by-step explanation:
The slope of a line can be calculated with the formula (y2-y1)/(x2-x1)
In this case we have:
(-4-(2))/(7-5)
(-6)/(2)
-3

I think you need to add them all up first or do the 90 degree
Answer:
(-2,6)
Step-by-step explanation:
Answer:
The value of x is 30°
Step-by-step explanation:
X° + 90° = 129° (Exterior angle property)
x° = 129° - 99° = 30°
<u>x°</u><u> </u><u>=</u><u> </u><u>3</u><u>0</u><u>°</u>
Hope it helps:)
