I need to know how to do the answer and why that’s the anwer
Pavel [41]
Ok so the answer is
4 {x}^{2}

so we multiply numbers that have the same variable

2 {x}^{3} \: \: \times {2x}^{ - 1} \\ \\
multiply 2 x 2

2 \times 2 = 4
then multiply the exponents

x ^{3} \times x ^{ - 1}
multipling like this will look like addition.
{x}^{3} \times {x}^{ - 1} = {x}^{2}
so in other words you could do it like this too
{x}^{3} + {x}^{ - 1} = {x}^{2}
now add the exponent with 4
4 + {x}^{2} = 4x ^{2}

now for the last part
{y}^{3} + {y}^{ - 3} = 0
because -3 and 3 added together make 0
0 + 4 {x}^{2} = 4 {x}^{2}
I hope this help(it looks complicated but it's very easy and I hope I helped you out)

REY [17]

Answer:

13,363.84 square cm

Step-by-step explanation:

For this question,

The circle table has a radius of 56 cm and the height of the edge of the cloth is 10cm(height) below the tabletop, which is a rectangle

We need to find out the area of a circle, Then the area of the rectangle.

Area of circle FORMULA= πr^2 | Area of rectangle FORMULA = l * h

πr^2

3.14 * 56 * 56 = area of circle = 9,847.04

[(2*3.14*56)Perimeter of circle which is also length of rectangle] * 10 = area of rectangle = 3516.8

9,847.04 + 3516.8 = 13,363.84
