Add the following polynomials

( -5m) + ( - 2m) + ( - m)
​

-8m

Step-by-step explanation:

7m³

Step-by-step explanation:

the answer is 7m³

- - =+

-5m+-2=7m²

7m²+-m=7m³

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
