Find and simplify an expression for the area of three rows of m squares with side lengths of m centimeters. Please help
Anna [14]

Answer:

3m²

Step-by-step explanation:

A square is quadrilateral (four sides) in which all sides are equal. Also, opposite sides are parallel to one another and all the four angles in a square are 90 degrees each.

The area of a square is given as:

Area = length * length

Given that the square has side lengths of m centimeters, therefore:

The area of each square = m cm × m cm = m² cm²

There are three rows of m squares, hence the total number of square is:

Total square = 3 rows * m squares per row = 3m squares

The total area of the square = area of each square * total number of square = m² * 3m = 3m² cm²

Can someone solve this for me with their explanation please?
Lana71 [14]

First you want to subtract 36

so it looks like this \sqrt[4] {(4x+164)^3}=64

Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)

{(4x+164)^3}=64^4 which is equal to {(4x+164)^3}=16777216

Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]

Then you end up with the equation 4x+164=256

Then subtract 164 to both sides

4x=92

then divide 92 by 4

Then you get x=23
