subtract 13 from 30, and you get 17. Then you need to divide 17 and 30
Answer:
X=16
Step-by-step explanation:
Solve 3(x-9)=21 IF X = 16
16-9 = 7
3X7= 21
Subtract 3x from both sides:
-6y = -3x + 6
divide both sides by -6 to get y by itself:
y = 1/2x - 1
function notation is rewriting y as a function:
f(x) = 1/2x -1
The answer is b (I think not really sure)
First, find the area of each of the prisms sides
5 by 5.5 = 27.5
3 by 5.5 = 16.5
4 by 3 cut in half = 6 (theres 2 of thoses so 12)
4 by 5.5 = 22
Add up the products and the surface area is 78 units
