Answer:
the last option is the answer
Step-by-step explanation:
The length is 15 inches and width is 9 inches
Step-by-step explanation:
Let
l be the length
and
w be the width
w = l-6
The area of rectangle is 135 ft^2
The formula for area is:
As the length cannot be negative, so we will use the value of length 15
If length 15,
w=l-6
w=15-6
w=9
So,
The length is 15 inches and width is 9 inches

A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.
Step-by-step explanation:
The inequality is given as;
-3x-7<20 which can be solved as
-3x < 20+7 -----collecting like terms
-3x < 27 -------divide both sides by -3
x > -9 -----change the sign direction because you divided by
plotting the solution x > -9 on a graph tool gives

Answer:
90°
Step-by-step explanation:
Two lines intersect each other at a right angle, making them perpendicular. Thus, the resulting angles will all be 90°, making ∠4 = 90°.
Alternatively, we can use the supplementary angles equation.
Let's call the right angle marked in the picture ∠5.
∠4 + ∠5 = 180°, since the line is also a straight angle which measures 180°.
∠4 + 90° = 180°
∠4 = 90°
Either way, ∠4 = 90°
