Answer:
I got -8m+24-32n
Step-by-step explanation:
8 and m equals 8m and since its negative 8 you add a negative sign: -8m
A negative and a negative equals a positive so its a positive sign and it equals +24:+24
A negative and a positive equals a negative so its minus 32n since the 4 includes an n:-32m
A^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 137^2 - 105^2
b^2 = 18769 - 11025
b^2 = 7744
b = sqrt 7744
b = 88
Gina's step is not correct... the length of the unknown leg is not 7744, it is the sqrt of 7744, which is 88
1. Volume of the sphere

Choice c
2. Algebra making a token effort to pretend to be geometry. Complementary angles add to 90 degrees.
(x+1) + (x-3)=90
2x -2 = 90
2x = 92
x = 46
Angles x+1=47 and x-3=43
Choice b
3. midpoint A=-5, E=5
The midpoint is just the average of A and E, here zero, point D
choice b
4. I can't really tell if x is supposed to be an angle or a length in this figure; presumably a length. I suppose we're to assume parallel lines; so this makes similar shapes, i.e. a proportionality:


Choice a
You could divide the result (14) by 7
