Answer:
a) 7x^2 + 5x
Step-by-step explanation:
(9x^2 + 8x) – (2x^2 + 3x)
Distribute the minus sign
(9x^2 + 8x) – 2x^2 - 3x
Line them up vertically
(9x^2 + 8x)
– 2x^2 - 3x
-------------------
7x^2 +5x
Answer:
The correct answer is the last choice. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.
Step-by-step explanation:
In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.
In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words, it didn't move.
In the last segment, it moved up again for 2 hours.
Answer: There are 4 terms in the Algebraic expression.
Answer:
see below
Step-by-step explanation:
5/8+ 3/8
Since the denominator is the same, we can add the numerators
(5+3) /8 = 8/8 = 1
5/8- 3/8
Since the denominator is the same, we can subtract the numerators
(5-3) /8 = 2/8 = 1/4
