Answer:
x = 100
Step-by-step explanation:
I know that the total is 180 so with that in mind this is what i did to get the answer.
180 - 57 = 123
123 - 23 = 100
Double check your work
100 + 23 = 123
then 123 + 57 = 180
your answer is 100:)
hope this helped!
General Idea:
The angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles. The theorem says that when the lines are parallel, that the alternate interior angles are equal.
Applying the concept:
Angles PBC and BAD are congruent by the <u>Corresponding Angle Theorem</u>.
Angles ABC and BAT are congruent by the <u>Alternate Interior angle Theorem</u>.
Answer:
5 (x + 1) (4 x^2 - 5 x + 3)
Step-by-step explanation:
Simplify the following:
(4 x^2 - 5 x + 3) (5 x + 5)
Factor 5 out of 5 x + 5:
Answer: 5 (x + 1) (4 x^2 - 5 x + 3)
Answer:
A
Step-by-step explanation:
We know the y intercept is positive so that eliminates choice D.
y = 3x^2 -2x+1
This does not intercept the x axis
y = 3x^2 -6x+3
= 3(x^2 -2x+1)
3(x-1)^2
This intercepts the x axis at 1
This is not the equation for the graph
y = 3x^2 -7x+1
Let x = 1
y = 3-7+1
= -3
This will cross the x axis, so this cannot be the graph
