Answer:
30
Step-by-step explanation:
Him plus his friend equals 5 and 150/3 is 30
So 150 divided by 5 is 30
Answer:

Step-by-step explanation:
Given m = - 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
Draw the figure out and you will find that AB + BC = AC. Given this, put the equations together to form x+41+x+10=22. Solve to get x=-29/2
Answer:
b = 40 and -40
Step-by-step explanation:
General form of Perfect square trinomial is a 2 + 2 a b + b 2
Therefore from 16 x 2 − b x + 25 a 2 = √ 16 x 2 , b 2 = 25 , then a = ± 4 x , b = ± 5 take consideration a=4x and b=-5 (different sign), then − b x = 2 ( 4 x ) ( − 5 ) − b x = − 40 x b = 40
The perfect square is ( 4 x − 5 ) 2 = 16 x 2 − 40 x + 25 .
if we consider a=4x and b=5 (same sign), then − b x = 2 ( 4 x ) ( 5 ) − b x = 40 x b = − 40
The perfect square is ( 4 x + 5 ) 2 = 16 x 2 + 40 x + 25 .
The first solution ( 4 x − 5 ) 2 is the best solution after comparing the expression given. I hope this helps, xx .
Answer:
a = 10.5 feet
Step-by-step explanation:
Given that,
The area of a square room, A = 110.25 ft²
We need to find the side length of the living room. Let the side be x.
We know that,
The area of a square, 
So,

So, the side length of the living room is equal to 10.5 feet.
