Witch expression is equal to 60-3y-9 a. 3(17-y)
b. 3(20-y)
c. 17 (3-y)
d. 20 (3-3y) -9

correct answer is: A

Step-by-step explanation:

1 - Commonn Factor is 3, so take out the 3

    3(20-y-3)

    3(17 - y)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
