Answer:
I suppose you mean 999^2
(1000-1)^2
which comes under the identity
(a-b)^2=
(a^2 + b^2 - 2ab)
hope this helps
Answer:
4
Step-by-step explanation:
Answer:
Step-by-step explanation:
2x-y=4 ..........(1)
x+y=5 ...........(2)
<u>Add equation 1 and 2:</u>
We get:
3x=9
x=9/3
x=3
Substitute value of x in (2):
x+y=5
3+y=5
y=5-3
y=2
(3,2)
Answer:
b
Step-by-step explanation:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
2x multiplies to all numbers:
2x x 8x3 = 16x4
2x x 6x2 = 12x3
2x x -10x = -20x2
Answer: 16x4 + 12x³ - 20x²
Hope this helps :)
