A=30^2+ 2 x 30 x 26
A= 900 + 1560
A= 2460
so the surface area is 2460
v=1/3 x 30^2 x 26
v=1/3 x 900 x 26
v= 300 x 26
v=7800
so the volume is 7800
and the way the order of operations helped you is that you had to remember to always do the exponents before any of the other multiplication
Answer:
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
It's literally the same equation written in reverse, which according to the commutative property, can be done.
Write an equation of the direct variation that includes the given point (-8, -4)
Direct variation is y= kx for some constant k
Find k using the point (-8,-4)
y=kx
(-4)=k(-8) substitution
-4/-8=k(-8/-8) division property
1/2=k
equation of direct variation is y=1/2k
