R(x)-c(x)=x²-30x+20 choose C
Answer:
please friend write your question clearly than I will answer your questions
The theorem is: a^2 - b^2 = (a+b) (a-b)
So, let's do this:
64x^2 - 49=
(8x)^2 - (7)^2=
(8x+7) (8x-7)
Answer:
no
Step-by-step explanation:
30 cents < 10 cents/dime × d dimes < 1 dollar × 100 cents/dollar
if d = 10
30 cents < 10 cents/dime × 10 dime < 1 dollar × 100 cents/dollar
30 cents < 10 cents/dime × 10 dime < 1 dollar × 100 cents/dollar
notice how the units bolded all cancel out, just leaving cents
30 cents < 100 cents is NOT < 100 cents
You could use the solution of 9/4 times 2
