The answer is a = 2.25.
Simplifying
7 + -4(3a + -5) = 0
Reorder the terms:
7 + -4(-5 + 3a) = 0
7 + (-5 * -4 + 3a * -4) = 0
7 + (20 + -12a) = 0
Combine like terms: 7 + 20 = 27
27 + -12a = 0
Solving
27 + -12a = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-27' to each side of the equation.
27 + -27 + -12a = 0 + -27
Combine like terms: 27 + -27 = 0
0 + -12a = 0 + -27
-12a = 0 + -27
Combine like terms: 0 + -27 = -27
-12a = -27
Divide each side by '-12'.
a = 2.25
Simplifying
a = 2.25
In a 30-60-90 triangle, the side lengths are in the ratio 1:2:sqrt(3) = short leg: hypotenuse: long leg.
We know the hypotenuse is 8. We can use this to find the other legs.
The short leg s is 8/2 = 4 because the short leg is always half of the hypotenuse.
The long leg q is 4 * sqrt(3), because the long leg is always sqrt(3) times the shorter leg.
So:
s = 4
q = 4 * sqrt(3)
A p + 10. Addition is having/giving more. Lynn has more then Carol, so if she has 30, Lynn has 40. So the answer is A.
