Answer: D. Subtracting 9 from each side
Step-by-step explanation:
Always start with numbers without variables first before doing anything with x. And make sure one side must not equal 0 unless you're doing polynomials.
A unit fraction means that the fraction has 1 in the numerator. To make 3/8 a unit fraction, you have to make it 1/8 by dividing by 3.
So now you have 3 x 3 x 1/8. You can multiply the 3 and 3.
You are left with 9 x 1/8.
Answer:
c)A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
Step-by-step explanation:
A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
The volume of a cylinder is given by V=Bh or V=πr²h
where B is the area of the base and h is the height of the cylinder.
V=πr²h-------equation1
V= π(w³ +2w² )--------- equation2
Comparing equation 1 and equation 2
πr²h=π(w³ +2w² )
r²h=(w³ +2w² )
r²h= w²(w +2 )
Taking w² common leaves w+2 which gives the height or length of the cylinder.
Therefore radius = width and height = length which gives the volume of the cylinder.
Answer:
C
Step-by-step explanation:
We know that the value of 1 is 4,
So, there are 2 difference,
1 is 4
2 is 6
3 is 8
4 is 10
5 is 12
So, the first five terms is 4, 6 ,8 ,10, 12.
