Answer:
Step-by-step explanation:
It doesn't look right to me, but you may not have the choices I would want to use. I think it should go
1/2
cos^2
sqrt(x)
+ 2)
The square root covers just the x, and nothing more.
6x^2 + 23x - 4 = 0
factorising:-
(6x - 1)(x + 4 ) = 0
x = 1/6 , - 4
Answer:
30"
Step-by-step explanation:
We know:
E = 3*s - 11
E = 79"
Setting them both equal:
79 = 3s - 11
add 11 to both sides
79 + 11 = 3s - 11 + 11
Simplify
90 = 3s
divide both sides by 3
90 / 3 = 3s / 3
Simplify
s = 30"
