Step-by-step explanation:
We have given expression
(a) We have to find the value of a
We know the property of exponent that when there is multiplication of two function then there is addition of exponent
So
(b) We use the property of exponent that when there is multiplication of two function then there exponent are added
Answer:
Option C.
Step-by-step explanation:
Consider the complete question is "Triangle JKL is transformed using the rule . Point K of the pre-image is at (4, 7). What are the coordinates of point K'' on the final image?".
According to , we get
According to , we get
The rule means first reflection and then rotation.
We need to find the image of K(4,7).
After reflection, we get
After rotation, we get
Therefore, the correct option is C.
Answer:
-48x^2 -666x+84
Step-by-step explanation:
Exponet is ^2.
Multiply is •
Use Distributed Property. Multiply the second parathesis by each term from the first parathesis.
Any expression multiplied by 1 remains the same. Distribute 41 through the parathesis. 41(2-7x-9x).
Distribute 3x through the parathesis 3x • (2-7x-9x).
You will have these numbers left: (Slide 2)
Add the numbers, 2 and 82 to get 84. Add -7x -9x + -287x -369x + 6x to get -666x. Add -21x^2 - 27x^2 to get 48x^2.
Use the communitative property to reorder the terms. And then your answer is -48x^2 -666x+84.
