Answer:

The square root of x will be evaluated first before the addition of 5. Hence (-3)^2 = 9 and 9 +5 = 14, as per your teacher's answer, which is correct. The answer would not be -4.

Find x, y, and z. ⠀⠀⠀⠀⠀⠀⠀⠀
fomenos

Answer:

Not sure but :

Y=15/7

X=13/5

Z=26/7

I will check them later and tell you if they are right or not .

Step-by-step explanation:

y power 2 : 31 × 8 = 248

Rad 248 = 15/7

x power 2 : 23 × 8 = 184

Rad 184 = 13/5

31 power 2 : (15/7) power 2 + z power 2

961 = 246/49 + z powe 2

z power 2 = 714/51

rad 714/51 = 26/7

z = 26/7
