Perimeter = 4*(3*x+2) = 12*x +8

So 12x +8 is the answer.

A store sold 6/1/cases of juice on Friday 4/4/5 cases of juice on Saturday. How many more cases of juice did the store sell on F

VikaD [51]

Data incomplete in question.

Question:

A store sold $6\frac{1}{5}$ cases of juice on Friday $4\frac{4}{5}$ cases of juice on Saturday. How many more cases of juice did the store sell on Friday than on Saturday?

Answer:

$1\frac{2}{5}$ cases of juice sold on Friday than on Saturday.

Solution:

Let us first change mixed fraction into improper fraction.

Number of cases sold on Friday = $6\frac{1}{5}=\frac{31}{5}$

Number of cases sold on Saturday = $4\frac{4}{5}=\frac{24}{5}$

Difference between cases sold on Friday and on Saturday

$$=\frac{31}{5}-\frac{24}{5}$

$$=\frac{31-24}{5}$

$$=\frac{7}{5}$

$$=1\frac{2}{5}$

Hence $1\frac{2}{5}$ cases of juice sold on Friday than on Saturday.

A rectangle has a length (x2 + 4y) unit and a breadth of (-2x + y3) unit. Find its perimeter

Ivahew [28]

Step-by-step explanation:

how do we find area? Length x width, right?

Let's break up each part.

3x3y2 = 3(x)(x)(x)(y)(y)

5x2y3 = 5(x)(x)(y)(y)(y)

Combining everything we have, 3(5)(x)(x)(x)(x)(x)(y)(y)(y)(y)(y). That's 15x5y5.

We multiply the coeffiecients and add exponents with the same base.

Hope this helps!

Answer:

960

Step-by-step explanation:

it says use 3 for pi, so you plug the values into given equation

V = 3·(4)²·20

r is 4 because it is half of 8.

Then multiply

3·16·20 = 48·20 = 960
