Answer:
v = 6
Step-by-step explanation:
3/v = 2/4
We can use cross products to solve
2v = 3*4
2v = 12
Divide each side by 2
2v/2 = 12/2
v =6
Answer:
1. X^2+1/2x =
2. X^2+2x-3 =
3. (2x-3)^2 = (2x-3)(2x-3)
4. X^3+2x^2-19x-20 =
Step-by-step explanation:
Each expression can be written as a product of linear factors as follows
1. X^2+1/2x ⇒
=
Hence, X^2+1/2x =
2. X^2+2x-3 ⇒
Hence, X^2+2x-3 =
3. (2x-3)^2 ⇒
Hence, (2x-3)^2 = (2x-3)(2x-3)
4. X^3+2x^2-19x-20 ⇒
First,
∴
Hence, X^3+2x^2-19x-20 =
