Your neighbor has a square table with the side lengths 4a^3. What is the area of the table?

vazorg [7]

Answer:

Area of a square table = A = $16a^{6}$

Step-by-step explanation:

Let,

Length of a table = l

Area of a square table = A

Given Data:

Length of a table = l = $4a^{3}$

To find out:

Area of a square table = A = ?

Formula:

Area of a square table = A = l×l

Solution:

Area of a square table = A = l×l

Area of a square table = A = $4a^{3}$ × $4a^{3}$

Area of a square table = A = $16a^{6}$

Help me guys show your solution and answer the qquestion

Luda [366]

Step-by-step explanation:

Line2

x - y = 3/2
x = y + 3/2

Line 3

3x + 2y = 6
3x = -2y + 6
x = -2/3y + 2

Line 4

1/4x + y = 2
y = -1/4x + 2

Line 5

4x - 3y = -33
3y = 4x + 33
y = 4/3x + 11

Questions

1. Yes. You need to isolate the variable to find and simplify.
2. To solve for x would require to multiply all terms by 4 to get rid of fraction
3. It wouldn't be easy because of the fraction. To make it easier would use multiples of 3 for x.
