Answer:
3rd choice
Step-by-step explanation:
In division for variables with same base, you do subtract top exponent minus bottom exponent. She did that correctly since -3-(-1)=-3+1=-2 and -2-1=-3.
The problem said m=-2 and n=4 and she replace m with (-2) and n with (4). She did this correctly.
You can multiply base numbers unless the exponents are the same 4 doesn't have the exponent -2 on it so you can't do (4(-2))^(-2)
The error is the 3rd option.
f(0) means x = 0
Since x = 0 less than 2 so we are using f(x) = -x + 2
Substitute x = 0 into f(x) = -x + 2
f(0) = -0 + 2
f(0) = 2
Answer
2
Answer:
n = 6
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
6n = 36 ( divide both sides by 6 )
n = 6
