Answer:
(x-2)(5x-8)
Step-by-step explanation:
x(5x-8)-2(5x-8)
Since both have 5x-8 we can factor by grouping.
(x-2)(5x-8)
Let x be number of downloads of standard version and y be number of downloads of high quality versions.
The hight quality downloads are twice as the standar downloads. So,

The downloaded data for x standard version is 2.7x and for y high quality version is 4.2y. The total downloaded data is 3219. So,

Substitute 2x for y in the equation and solve the obtained equation for x.

So value of x is 290. Thus downloads of the standard version were 290.
Answer: 290
Answer:
y= -2/3x+11/3
Step-by-step explanation:
Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1
