Answer:
A. −19z − 77
Step-by-step explanation:
−9(z + 3) − 5(2z + 10)
The first step is to distribute
-9*z -9*3 -5*2z -5*10
-9z-27 -10z-50
-19z -77

I know I'm right for sure
We will use the Unitary method to solve this question
304/4=76
Therefore The train travels 76 miles per hour
76*7.5=570
Therefore the train travels 570 miles in 7.5 hours
Answer:
The rug has covered approximately 95 square feet of the living room.
Step-by-step explanation:
Given:
Diameter of rug = 11 feet
We need to find the area covered in living room by the rug.
Solution:
Diameter of rug = 11 feet
Radius is half of the diameter.
Radius of the rug = 
Now it has been given that rug is in circular shape.
So we will find the area of the rug using Area of circle formula which is given by π times square of the radius.
Framing in equation form we get;
area of the rug = 
Hence The rug has covered approximately 95 square feet of the living room.
Answer:
( x + 36 ) ( x - 2 ) = 0
Step-by-step explanation:
x^2 + 36x - 2x -72 = 0
x ( x + 36 ) - 2 ( x + 36 ) = 0
( x + 36 ) ( x - 2 ) = 0
