Step-by-step explanation:
Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S
so we get as,
==> x+7 = (-2)^5
==> x+7 = -32
==> x = -32-7
==> x = -39
hence, x = -39
Option A.) is correct.
Answer:
I think it is 8, i did not learn this in school
Step-by-step explanation:
2(3x^2+5)
6x^2+10
4m-10m=5-2
-6m=3
m=-3/6
M=-1/2
Now let's check if this is correct-6•(-1/2)=6/1•1/2=6/2=3 ,yes correct I think
z score = (1300-1700)/75
z score = -400/75 = -5.33
