Wait what are trying to answer here
A = 2πrh + 2πr^2 is the formula. Where A = surface area, r = radius, and h = height. So all we need to know is the outer radius, which is 3.5. Hope this helps you.
Answer:
B, C, and D are all equivalent to 3(4h+2k)
Step-by-step explanation:
We use the distributive property to say 3(4h+2k)=12h+6k
"A" distributes to 12k+6h
"B" distributes to 12h+6k
"C" distributes to 6k+12h (associative property works)
"D" is already distributed to 12h+6k
So A is wrong, and B, C, and D are right
Hope this made sense!
Answer:
x=4, y=1
Step-by-step explanation:
x + 3y = 7
x - 3y = 1
Add the equations together to eliminate y
x + 3y = 7
x - 3y = 1
---------------------
2x = 8
Divide by 2
2x/2 = 8/2
x = 4
Subtract the two equations to eliminate x
x + 3y = 7
-x + 3y = -1
----------------------
6y = 6
Divide by 6
6y/6 = 6/6
y =1
The new points will be A' (-6,9) B'(-6,-3)C'(6,-3) then graph them. REMEMBER: if the scale factor is greater than 1 the image will shrink. If the scale factor is less than one the image will enlarge
