Answer:

2,-12

Step-by-step explanation:

The given equation is ,

\implies |x + 5 | = -7

We know that modulus only gives positive value , Therefore on squaring both sides we have ,

\implies (x + 5 )^2=( -7)^2 \\\\\implies (x+5)^2=7^2\\\\\implies x + 5 =\pm 7 \\\\\implies x = 7-5,-7-5 \\\\\implies \boxed{ x = 2, -12}

What is the Mean, Mode, and Median of this set? <br><br> 23, 34, 54, 43, 46, 27, 29
Alecsey [184]
43 is the median, the mean is 36.6 (36.57 rounded up) and since none of the numbers repeat, there isn't really a mode.
Hope this helps
