(a) Without solving the equation we can't determine whether its true or false.
(b) If x = 3
4x + 1 = 2x + 5
4(3) + 1 = 2(3) + 5
12 + 1 = 15 + 5
13 = 20
No, if x = 3, the equation will not be true.
(c) 4x + 1 = 2x + 5
4x - 2x = 5 - 1
2x = 4
x = 4/2
x = 2
This shows that x = 2 makes the equation true.

Answer:
? = 22y^2
Step-by-step explanation:
Ask yourself, what times 20y will get me 40y^3?
The answer to this would be 2y^2.
When you multiply something to the denominator, you also have to do so to the numerator. Therefore, you are required to multiply 2y^2 to the 11 to get your '?' value.
11 x 2y^2 = 22y^2
