Answer:
1) 48p^2+4p-4
2)40b^2-45b+5
3)3p^2-6p+3
4)3v^2-6v+3
5)40x^2+28x+24
6)3x^2+15x+12
Step-by-step explanation:
Remark
The proof is only true if m and n are equal. Make it more general.
m = 2k
n = 2v
m + n = 2k + 2v = 2(k + v).
k and v can be equal but many times they are not. From that simple equation you cannot do anything for sure but divide by 2.
There are 4 combinations
m is divisible by 4 and n is not. The result will not be divisible by 4.
m is not divisible by 4 but n is. The result will not be divisible by 4.
But are divisible by 4 then the sum will be as well. Here's the really odd result
If both are even and not divisible by 4 then their sum is divisible by 4
Answer:
(a) 3 - 2x - 2x² (b) -21
Step-by-step explanation:
given, y +2x² = 3 -2x
make y the subject:
y = 3 - 2x - 2x²
if y = f(x)
then
f(x) = 3 - 2x - 2x²
(b)<u> to find f(3) we need to replace x with 3:</u>
<u />
3 - 2(3) - 2*(3)²
-21
The answer equals to 13 1/20 or in decimal form 13.05
First of all, we need to know:
3^3 = 3 x 3 x 3 = 9 x 3 =
27So:
So, your answer is
D.
