Complementary angles are angles that add up to 90 degrees. 2x is the first angle. Let y be the second one.
y+2x = 90
Subtract 2x from both sides.
y = 90 - 2x.
The second option is your answer. Have is nice day! :)
Answer:
B
Step-by-step explanation:
Answer:
mean= 90
Step-by-step explanation:
The mean is the terms added together, then divided by the number of terms (in this case, 8):
Done.
Answer:
The polynomial is ;
x^3 -2x^2 -13x - 10
Step-by-step explanation:
Given the zeros, we set them to equal zero so as to get the linear factors
Mathematically, that will be as follows;
x = -2
x + 2
x = 5
x-5
x = -1
x + 1
So we have the polynomial as;
(x + 1)(x + 2)(x-5)
= (x -5)(x^2 + 3x + 2)
= x^3+ 3x^2 + 2x -5x^2 -15x - 10
= x^3 -2x^2 -13x - 10
