1. What is the value of n in -57 - n = -144?
A-201
B-87
C 87
D 201

C=87

Step-by-step explanation:

To isolate the variable, you need to take away -57 by adding it to -144.

Then, you'd see:

-n=-87

Next, you divide both sides by -1 to get 87

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
