Can anyone help I could really use it

-12m-6n

Step-by-step explanation:

Let's break this down systematically

Start:

8m + 2n - 4(5m - 2n)

Use the distributive property

8m + 2n - 4(5m - 2n)

8m + 2n - 20m - 8n

Match like terms m and n

8m - 20m = -12m

2n - 8n = -6n

-12m-6n

y = x + 95

y = 42 + 95

y=137 mm hg

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
