-3/4 x -2/5

When you multiply fractions multiply the two top numbers and then the two bottom numbers.

-3 x -2 = 6

4 x 5 = 20

-3/4 x -2/5 = 6/20 which reduces to 3/10

Answer: 3/10

Answer: 3 / 10

Step-by-step explanation:

<u>Given word expression</u>

negative 3 over 4 multiple by negative 2 over 5

<u>Convert to numerical expression</u>

(-3/4) × (-2/5)

<u>Multiply numerator by numerator and denominator by denominator</u>

<u>(REMEMBER to change the [+] sign when two [-] signs are multiplied together)</u>

(3 × 2) / (4 × 5)

6 / 20

<u>Divide 2 on both numerator and denominator</u>

(6 ÷ 2) / (20 ÷ 2)

$\boxed{\frac{3}{10} }$

Hope this helps!! :)

Answer:

Step-by-step explanation:

If you simplify the equation you get $\sqrt{\frac{x+3}{1-x} }$ . To solve a square root function, you need to set up $\sqrt{\frac{x+3}{1-x} }\geq 0$ . You can take the square root of both sides to get $\frac{x+3}{1-x} \geq 0$ . Then, we identify the intervals that will satisfy the equation, which is -3 ≤ x < 1.
