Angles 1 and 3 are alternate interior angles which is why they are congruent
Answer:
x times 2y times pi
Step-by-step explanation:
The formula is height times diameter times pi. diameter is two times the radius, and 2 times y is 2y. the rest is simple. multiply them together an you get the answer
An equation that goes through (-2, 1) and has a slope of 4 is y = 4x + 9.
You can find this by looking for the y-intercept (b) by using the slope (m), the point and slope intercept form. The work is below for you.
y = mx + b
1 = 4(-2) + b
1 = -8 + b
9 = b
Now we can use that and the slope to create the equation y = 4x + 9
For this case we have the following expression:
-x (7x + 2) + x ^ 2
Rewriting we have:
(-7x ^ 2 -2x) + x ^ 2
Adding similar terms we have:
-6x ^ 2 - 2x
Answer:
The simplified expression is given by:
-6x ^ 2 - 2x
