<span>Given:
Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8.
Simplify Q - [R + S] - T.
Q-(R+S)-T
=</span>7m + 3n - (11 - 2m + n + 5 ) - (-m - 3n + 8)
=7m+2m+m + 3n-n+3n -11-5-8
=10m+5n-24
(x+3)(x+1)=(x+6)(x)
x^2+x+3x+3=x^2+6x
x^2+4x+3=x^2+6x
4x+3=6x
3=2x
x=1.5
Hope this helps :)
Answer:
t = 0
Step-by-step explanation:
t - 2 = - 2
t = - 2 + 2
t = 0
No because circumference is a whole different thing
