The answer is 131. Angle 1= 57, angle 2= 74.
Answer:
X=2
Step-by-step explanation:
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 = 
Answer:
fliped over y axis and moved up 3
Step-by-step explanation:
fliped over y axis (changed x to -x) and moved up 3 (changed +1 to +4)
Rate or velocity is always distance divided by time
369 km / 3 sec =
123 kilometers per second
