Step-by-step explanation:
(x+2y)(x-2y)
- x^2-2xy+2xy-(2y)^2
- x^2-4y^2
1. x^2 + x - 90
2. (x+10)(x-1)
3. x= -10 and 1
Solve the "f" function with substitute 4 and solve the "g" function with what we get for the "f" function.
f(4) = 2(8) + 3
f(4) = 16 + 3
f(4) = 19
g(19) = 4(19) - 1
g(19) = 76 - 1
g(19) = 75
Best of Luck!
Answer:
what exactly did u want me to work out?
Answer:
First of all, the numbers are all positive numbers
They can all be divided by the number 3
They are all rational numbers, this means that they can be expressed as a ratio of two numbers
