The best answer to go with is b you’re welcome have a great day
Answer:
Step-by-step explanation:
2x, x, and 3x all have to add up to equal 180 by the Triangle Angle-Sum Theorem.
2x + x + 3x = 180 and
6x = 180 so
x = 30
Therefore, angle B is 30.
Answer:
22 minutes to 7
Step-by-step explanation:
short hand is near 7
f(x) = (x + 5)(x - 1)
using the ' factor theorem '
given x = a is the root of a polynomial then (x - a ) is a factor
here roots are x = - 5 and x = 1 hence factors are (x + 5) and (x - 1)
the polynomial is the product of the factors
f(x) = (x + 5)(x - 1)
