Solve: |4x + 5| + 8 >(or equal to)45

KatRina [158]

This is pretty simple once you get used to this

First set it equal to the original and the negative one
(>_) is the bigger and equal to part

4x+5>_45 or 4x+5>_-45

Then solve for x for both

4x>_40. 4x>_-50
X>_10 X>_-25/2

The number of square tiles of side 25cm which can be paved on a rectangular floor of 3m

MA_775_DIABLO [31]

Answer:

96 square tiles can be paved on a rectangular floor.

Step-by-step explanation:

First, we need to find the area of the square tiles:

$A_{t} = (25 cm)^{2} = 625 cm^{2}$

Now, the area of the rectangular floor is:

$A_{f} = 3m*2m = 6 m^{2}*\frac{(100 cm)^{2}}{1 m^{2}} = 60000 cm^{2}$

Finally, the number of square tiles which can be paved on a rectangular floor is:

$N = \frac{A_{f}}{A_{t}} = \frac{60000 cm^{2}}{625 cm^{2}} = 96$

Therefore, 96 square tiles can be paved on a rectangular floor.

I hope it helps you!
