You're right but just to simplify your life, make the formula this...

A=2(wl+hl+hw)

w=width

h=height

l=length

Easy, just fill in the "variables."

Example,

l=2

w=2

h=2

Plug it in..

2(2*2+2*2+2*2)

2(4+4+4)

2(12)

24

Thus, your surface area example...

Easy.

Change the equation of the line to slope-intercept form. 6x + 2y =10 *
allsm [11]

Answer:

Solve for y.

Step-by-step explanation:

6x+2y=10

6x+2y-6x=10-6x  subtract 6x from both sides.

2y = -6x+10

2y/2 = -6x/2+10/2  divide each term by 2.

y = -3x+5

Hope this helps!
