Just wanted the points
Step-by-step explanation:
THANKS
The rate(speed) is 1 3/5
We can use the distance formula to solve:
d= rt
D= 4/5
T=1/2 hr
Substitute
4/5= 1/2t
Multiply 2 on both sides
2* (4/5)=(1/2)t * 2
8/5=t
We can simplify this to 1 3/5
Answer:
1. (2x - 2y)² - 9
2. 99099
Step-by-step explanation:
We know the a+b formula :
(a-b)² = a² - 2ab + b²
1. 4(x-y)^2 -9
4(x² - 2xy + y²) - 9
4x² - 8xy + 4y² - 9
(2x - 2y)² - 9
2. 1001 × 99
= 99099
