Aiden has a rectangle that is 8 centimeters long by 4 centimeters wide. He wants to divide the rectangle into squares with 1/2 centimeter side lengths. Will Aiden’s plan result in at least 200 squares?

128 squares

Step-by-step explanation:

If the rectangle is 8cm long by 4cm wide, the area is:

The squares have 1/2=0.5cm side length, hence the area of the squares is:

By dividing A between A' you can obtain the number of squares:

hence, the number of sqares that Aiden is able to produce is 128

No, Aiden's plan will be a maximum of 128 squares

Step-by-step explanation:

We have a rectangle with 8 cm long by 4 cm wide, that is to say

8*4 = 32 squares, but you want to divide the rectangle into 1/2 cm squares, therefore

So Aiden's plan will have to be limited to max 128 squares

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
