Answer:

144 m^2

Step-by-step explanation:

the front side is 9 m tall and 6 m long. The formula for the surface are of triangles is W*L/2, so 9*6=54, 54/2=27. Four sides are the same, so multiply 4 to get 108m. the the faced down part is 6m by 6m, so multiply 6*6 is 36, then add up 36 + 108 = 144m.

−13 = 5(1 + 4m) − 2m multi step equation show all steps pls

Radda [10]

Answer:

m = -1

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

-13 = 5(1 + 4m) - 2m

Step 2: Parenthesis (distribute)

-13 = 5 + 20m - 2m

Step 3: Combine like terms (m)

-13 = 5 + 18m

Step 4: Subtract 5 on both sides

-18 = 18m

Step 5: Divide both sides by 18

-1 = m

Step 6: Rewrite

m = -1

agasfer [191]

I do not know but i can give you about 2 - 3 tips.
First get a ruler and figure out how many centimeters are in a inch.
Then you will multiply 12 and how many centimeters are in a inch.
And that is how you will get your answer.
