Note, since both factors have the same denominator, we can add the numerators together.
Numerator :
5n + (2m + 4n) = 5n + 2m + 4n = 9n + 2m
Denominator :
30m
Thus,
= (9n + 2m) / 30m
X^4 because it has 4 zeroes ( the graph crosses the x axis 4 times
Just by the language difference means subtract,
Y^2-25 is the difference of squares
factored it's the sum and difference of their square roots
(x+5) (x-5)
Answer:
B
Step-by-step explanation:
Answer:
Number of coupons sent to Existing members = 33
Step-by-step explanation:
Number of coupons sent out = 231
Let :
6 times as many to potential members = 6 * X = 6X
while existing members = X
therefore 6X + X = 231
7X = 231
therefore X = 231 / 7 = 33
so existing members = 33
while potential members = 6 * 33 = 198
