Answer:
<em>I disagree with both solutions. The value of b that will make the expression correct is -30</em>
Step-by-step explanation:
Given the equation solved my Mai and Tyler expressed as:
2/5 b + 1 = -11
We are to check the veracity of the solutions;
2/5 b + 1 = -11
Subtract 1 from both sides of the expression
2/5 b + 1 -1 = -11-1
2/5 b = -12
Cross multiply
2b = -12 * 5
2b = -60
Divide both sides by 2
2b/2 = -60/2
b = -30
<em>Since the solution b = -25 and -28 does not tally with the gotten solution, I disagree with the both solutions</em>
Find critical points by setting derivative equal to 0.
Derivative of polynomial is found by multiplying coefficient by exponent, then subtracting 1 from exponent.
f'(x) = 5x^4 - 30x^2 + 9 = 0
This is in quadratic form, use quadratic formula to find x^2
109 divided by 9 is 12. So the answer is 9.

Answer:
x=65 degrees
Step-by-step explanation:
There is a theorem that states: The sum of an exterior angle of a triangle is equal to the sum of the nonadjacent interior angles.
Therefore:
2x-15= 50 + x
x=65
