Answer:
You already know the answer is -108
Step-by-step explanation:
There is probably a formula for finding the coefficient of a variable in an expansion. But (x-3) is easy to square, and that gives us
x^2 - 6x +9
Now to square that quadratic trinomial I used an area model. You can get the entire expansion. But we are just only interested in the x terms. See image. They are in yellow on the image. You can see we get -54x two times. So
-54x + -54x is the -108x term you are interested in.
Answer:
Secant
Step-by-step explanation:
Tangents are ongoing lines that occur on the outside of a circle.
A secant is an ongoing line that passes through a part of the circle that does not pass through the center.
A chord is a line of definite length that is entirely within the circle, stretching from one side to the other, but does not go through the center point of the circle.
To find the other endpoint with a given endpoint and midpoint, you subtract the midpoint values from the endpoint, then with whatever the answer is, you subtract that from the midpoint.
Answer:
The third option: 48 degrees.
Step-by-step explanation:
Angle GFH is congruent to angle CFE, which is congruent to ACB, therefore, all are congruent and equal to 48.
Answer:
The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values.
