Answer:
4m^4 - 8/3m^2 n^2 + 4/9n^4
Step-by-step explanation:
(2m^2 - 2/3n^2)(2m^2 - 2/3n^2)
= 2m^2(2m^2 - 2/3n^2) - 2/3n^2(2m^2 - 2/3n^2)
= 4m^4 - 4/3m^2 n^2 - 4/3m^2n^2 + 4/9n^4
= 4m^4 - 8/3m^2 n^2 + 4/9n^4
6a+15+5a-10
11a+5 this is the answer
87 is the mean.
To find the mean, you must
- add all of the numbers
- divide by the amount of numbers given
In this case, you would want to do (86 + 80 + 95)/3. This would give you an answer of 87.
Answer:
Option A.
Step-by-step explanation:
Properties of the similarity of two polygons,
1). All angles of one polygon will be equal to the angles of the other polygon.
2). Their corresponding sides will be in the same ratio.
If the measures of corresponding angles of KLMN and ABCD are equal, but the lengths of the corresponding sides of ABCD are half those of KLMN,
Then the polygons ABCD and KLMN will be similar.
Option A will be the answer.
Using shifting concepts, it is found that the correct option is:
B. The graph of f(x) is vertically compressed by a factor of 6 and shifted 9 units down.
---------------------------
- The parent function is .
- The first transformation is a multiplication by 1/6. Multiplying by 1/a is the same as vertically compressing by a factor of a, thus, it was vertically compressed by a factor of 6.
- Then, 9 was subtracted. When a is subtracted from the function, it means that it was shifted down a units, thus, it was shifted down 9 units, and the correct option is B.
