In the triangle below, what is the m

125

Step-by-step explanation:

The sum of all 3 interior angles of a triangle is 180.

18 + (12y + 5) + (4y - 3) = 180

20 + 16y = 180

Subtract 20 from both sides

16y = 160

Divide both sides by 16

y = 10

Now plug y back into equation for angle A

12y + 5

12(10) + 5

120 + 5 = 125

there are no figures how am i supposed to answer this question

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
