Given simplification:
3√7 + 7√63 + (√7/7)
= 3√7 + 7√(9*7) + (√7/7)
= 3√7 + 7*3√7 + (√7/7)
= 3√7 + 21√7 + (√7/7)
= (3+21)√7 + (√7/7)
= 24√7 + (√7/√7)
= (7*24√7 + √7)/7
= (168√7 + √7)/7
= (169√7)/7
<u>Answer</u><u>:</u><u>-</u> 3√7 + 7√63 + (√7/7) = (169√7)/7.

1/x - 2/(x-3) = 4
multiply each side by x*(x-3)
x*(x-3)(1/x - 2/(x-3)) = 4*x*(x-3)
distribute
x*(x-3)(1/x) - 2/(x-3))x*(x-3) = 4*x*(x-3)
cancel
(x-3) - 2*x = 4x(x-3)
distribute
x-3-2x = 4x^2-12x
combine like terms
-x-3 = 4x^2 -12x
add x+3 to each side
0 = 4x^2 -12x+x+3
0 = 4x^2 -11x+3
using the quadratic formula
x= 11/8 - sqrt (73)/8
x=11/8 + sqrt (73)/8
Answer:
40 choices of combinations can be made.
Step-by-step explanation:
Given that Brian wants to buy a shirt, and he can choose an XL, L, M, S, or XS long-sleeve or short-sleeve in white, black, pink, or blue, to determine how many choices of combinations does he have, the following calculation must be performed:
XL + L + M + S + XS = 5
LS + SS = 2
W + B + P + B = 4
5 x 2 x 4 = X
10 x 4 = X
40 = X
Thus, 40 choices of combinations can be made.
