Answer:

Thus # 2 is correct (5 (y + 4))/2

Step-by-step explanation:

Simplify the following:

(5 y (y^2 - 16))/(2 y (y - 4))

(5 y (y^2 - 16))/(2 y (y - 4)) = y/y×(5 (y^2 - 16))/(2 (y - 4)) = (5 (y^2 - 16))/(2 (y - 4)):

(5 (y^2 - 16))/(2 (y - 4))

y^2 - 16 = y^2 - 4^2:

(5 (y^2 - 4^2))/(2 (y - 4))

Factor the difference of two squares. y^2 - 4^2 = (y - 4) (y + 4):

(5 (y - 4) (y + 4))/(2 (y - 4))

Cancel terms. (5 (y - 4) (y + 4))/(2 (y - 4)) = (5 (y + 4))/2:

Answer: (5 (y + 4))/2

-40-2(3m+1/2)=7m-2 what does m equal

kherson [118]

Answer: $m$ = −3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Expand.

−40 − 6 $m$ − 1 = 7 $m$ − 2

Step 2: Simplify −40 − 6 $m$ − 1 to −6 $m$ − 41.

−6 $m$ − 41 = 7 $m$ − 2

Step 3: Add 6 $m$ to both sides.

−41 = 7 $m$ − 2 + 6 $m$

Step 4: Simplify 7 $m$ − 2 + 6 $m$ to 13 $m$ − 2.

−41 = 13 $m$ − 2

Step 5: Add 2 to both sides

−41 + 2 = 13 $m$

Step 6: Simplify −41 + 2 to −39.

−39 = 13 $m$

Step 7: Divide both sides by 13.

− $\frac{39}{13}$ = $m$

Step 8: Simplify $\frac{39}{13}$ to 3.

−3 = m

Step 9: Switch sides.

$m$ = −3
