Answer:

4x + 9 ≥ 0

Step-by-step explanation:

The inside of the square root, the radicand, cannot be negative.

It can only be zero or positive.

Zero or positive is also described as being greater than or equal to 0.

Set the radicand to be greater than or equal to zero.

4x + 9 ≥ 0

8/7=x/5 what is the value of x round to the nearest tenth
faust18 [17]

Answer:

<h2>x = 5.7</h2>

Step-by-step explanation:

\frac{8}{7}  =  \frac{x}{5}

To find x first cross multiply

We have

7x = 8 × 5

7x = 40

Divide both sides by 7

That's

\frac{7x}{7}  =  \frac{40}{7}

x =  \frac{40}{7}

x = 5.7142

We have the final answer as

<h3>x = 5.7 to the nearest tenth</h3>

Hope this helps you

The floor of the restaurant is a square of sides 28m. The floor is covered with square tiles of sides 40m. Calculate the total n
lisov135 [29]

Answer:

196000 tiles.

Step-by-step explanation:

The 28 m is 2800 cm. So a 28 x 28 meter square would be 2800 x 2800 centimeter square.

The tiles are 40 cm.

If you divide 40 from (2800 x 2800). (2800 x 2800) ÷40 = 196000

So 196000 tiles.

I'm not entirely sure if that's correct, but if it helps that's awesome.
