Answer:
is in proportion.
is not in proportion.
is in proportion.
is in proportion.
Step-by-step explanation:
The first example is and it is in proportion.
This is because, you will get the same simplest fraction (
) from the fraction 
by dividing its numerator and denominator by 5.
The second example is and it is not in proportion.
This is because, you can not get the simplest fraction (
) from the fraction 
after simplification.
The third example is and it is in proportion.
This is because, you will get the same simplest fraction (
) from the fraction 
by dividing its numerator and denominator by 2 and from the fraction 
by dividing its numerator and denominator by 3.
The fourth example is and it is in proportion.
This is because, you will get the same simplest fraction () from the fraction 
by dividing its numerator and denominator by 5. (Answer)
Answer:
9
Step-by-step explanation:
Equation
Sum = s = 180*(n - 2)
Solution
1260 = 180*(n - 2) Divide by 180
1260 / 180 = 180 * (n -2 ) / 180
7 = n - 2 Add 2 to both sides
9 = n
Answer
The polygon has 9 sides.
Answer:
2x^2 +11
Step-by-step explanation:
f(x) = 3x^2 +2
g(x) = x^2 -9
f(x) - g(x) = 3x^2 +2 - (x^2 -9)
Distribute the minus sign
= 3x^2 +2 -x^2 +9
Combine like terms
= 2x^2 +11
