Multiplication is when you times two different numbers together where its negative or postive(you can multiple pretty much anything together)but combining like terms are number or letters thats the same. For instance, say if i have 4x+7-2x+3, i would combine each term that has something in common with it,like, 4x and 2x because both has X and i will combine 7 and 3 because those two are regular numbers and does not have an X like the others. I Hope That helps!

The surface area of a cylinder is
where
is the radius of the base of the cylinder and
is the height of the cylinder.
So, the surface area of the cylinder is:







Answer:
a)x=5; b)x=4
Step-by-step explanation:
a) 4x-3=2x+7
=>4x-2x=7+3
=>2x=10
=>x=5 [divide both by 2]
b)2x+6=7x-14
=>7x-2x=6+14
=>5x=20
=>x=4 [divide both by5]
Answer:
R(x) = 8999.93x
Step-by-step explanation:
The original price is $9000 per unit. The unit is x, so if you buy x units, you pay 9000x.
The original price function is
R(x) = 9000x
The discount is 7 cents per unit bought, so if you buy x units, the discount is 9x in cents, or 0.09x in dollars. This discount is subtracted from the original price, so the discounted price is
R(x) = 9000x - 0.07x
R(x) = 8999.93x
Answer: R(x) = 8999.93x
