0.4 is four tenths. 0.4 = 4/10=2/5
F(x)=-4x-1 if you sub 3 into it you get 3(-4)-1 which is -13 and 2x+4=10
Answer:
20
Step-by-step explanation:
5 divided by 100 = 20
Wait for area, wouldn't you just times 13 and 5 and get 65 and then times 23?
Answer:
x = -7/2 multiplicity 2.
Step-by-step explanation:
4x^2 + 28x + 49 = 0
(2x + 7)(2x + 7) = 0
This is a perfect square.
2x + 7 = 0, so:
x = -7/2 multiplicity 2.
