Answer:
The coefficient of y² will be 1, which we can see when we expand the expression:
(x + y)²
= (x +y)(x + y)
= x² + xy + xy + y²
= x² + 2xy + y²
Answer:
10 days
Step-by-step explanation:
Jenny has read 50 pages and will read 15 each day.
The equation would be: 15x+50
Mark will read 20 pages daily.
The equation would be: 20x
In both equations x represents days.
You set both equal to each other because you want to know when they read the same amount of pages.
15x+50=20x
...you subtract 15x from both sides
50=5x
...and divide by five to get: 10 days
Well the first term = 1 because (n - 1) = 0 for the first term
So its either A or D
4th term = 1 + (4 - 1)(-5.7 = 1 + 3*-5.7 = -17.1
Its C
