Steps to solve:
-k^2 - (3k - 6n) + 2n; k = -3, n = -5
~Substitute ans simplify
-(-3)^2 - (3(-3) - 6(-5)) + 2(-5)
3^2 - (-9 + 30) - 10
~Use PEMDAS and solve the rest
9 - 21 - 10
-13 - 10
-23
Best of Luck!
Answer:
x=6
Step-by-step explanation:
I don't know what is between f(x) and g(x), so (for now) there are two posible answers:
1.

- function multiplication:

2.

- function composition:
I’m guessing that x is the angle on the right that isn’t shown?
Anyways if that’s the case then:
We know that the sum of all the angles of a triangle add up to 180 degrees.
In this triangle we know that one angle is 55 degrees and the other is 90 degrees, so to find the last angle we do the sum of all the angles and we remove the 2 angles:
180- (55+90)= 35 degrees.
x= 35 degrees
In this equation x = 49.
In order to find this, follow the order of operation of solving equations.
1/7x - 5 = 2 -----> Add 5 to both sides
1/7x = 7 ----> Multiply both sides by 7
x = 49
