The correct result would be y = -6/5 - (2 * sqrt(6))/5 and<span> y = (2 * sqrt(6))/5 - 6/5.

For this case we have the following quadratic expression:

(5y + 6) ^ 2 = 24

From here, we must clear the value of y.

For this, we follow the following steps:

1) We clear the square term:

(5y + 6)  =+/-\sqrt{24}

(5y + 6)  =+/-2\sqrt{6}

2) Pass the value of 6 by subtracting:

5y  =-6+/-2\sqrt{6}

3) Pass the value of 5 to divide:

y  =\frac{-6+/-2\sqrt{6} }{5}

Answer:

The solutions to the quadratic equation are:

y  =\frac{-6+2\sqrt{6} }{5}

y  =\frac{-6-2\sqrt{6} }{5}

Order Of operation.
Nikolay [14]

Answer

18(2)+12(2)-4(5)

36+24-20

60-20

40

Step-by-step explanation:

since they had two-18 yard passes and two 12 yard runs, that's the first part of the expression, and then they had four penalties that cost them 5 yards, and that was the last term. When you simplify, you end up with 40 yards gained.

In math

Passes: 18(2)

Runs: 12(2)

Penalties:4(5)

equation

18(2)*12(2)-4(5)

Hope it helped

Liono4ka [1.6K]

Answer:

The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides

She wrote 5/4+3/4 instead of 5/4-3/4

Step-by-step explanation:

Correct solution:

\frac{3}{4}  + m =   \frac{5}{4}

Subtract-3/4 from both sides

\frac{3}{4}  -  \frac{3}{4}  + m =  \frac{5}{4}  -  \frac{3}{4}

Simplify

m =  \frac{5}{4}  -  \frac{3}{4}  \\ m =  \frac{1}{2}
