Mathematics

Alexxandr [17]3 years ago

The given expression is

(x+4)(3x^2 +2x)

And in the second factor, x is common. So on taking x out, we will get

(x+4)(x)(3x+2) = x(x+4)(3x+2)

We can expand it by distributing , that is

(x+4)(3x^2 +2x) = x(3x^2 +2x) +4 (3x^2 +2x)

= 3x^3 +2x^2 + 12x^2 +8x

Combining like terms,

= 3x^3 +14x^2 +8x

And that's the expanded form ., and the given expression can also be written in that way .

You would plot them by month, 170-110= 60 dollar increase. 60 divided by 12 ( for each month) leaves a 5 dollar increase each month. Your coordinates would be 0,110 1,115 2,120 3,125

Which values of x and y are solutions to the open sentence?       4y ≥ 3x + 2   A. x = 3, y = 0   B. x = 4, y = 3   C. x = 6, y
kobusy [5.1K]
Your answer would be C. x = 6, y = 5
This is because if you plug the numbers in to the inequality, we get:
(4 × 5) ≥ (3 × 6) + 2
20 ≥ 18 + 2
20 ≥ 20
which is correct.

I hope this helps!
