Yumi and Juan pick up litter along the highway at the same rate. Yumi picks up litter for 3 miles and takes two hours longer tha

Harlamova29_29 [7]

3/(x+2) = 2/x

multiply both fractions by x(x+2) to cancel out the bottoms

so it becomes 3x = 2x+4

ow subtract 2X from both sides and you get

x = 4

so it took Juan 4 hours

it took Yumi 2 hours more so 4+2 = 6 hours

What is true about the completely simplified sum of the polynomials 3x^2y^2-2xy^5 and -3x^2y^2 + 3x^2y^2 + 3x^4y?

WINSTONCH [101]

Given:

The polynomials are:

$3x^2y^2-2xy^5$

$-3x^2y^2+3x^2y^2+3x^4y$

To find:

The completely simplified sum of the polynomials.

Solution:

We have,

$3x^2y^2-2xy^5$

$-3x^2y^2+3x^2y^2+3x^4y$

The sum of given polynomials is:

$Sum=3x^2y^2-2xy^5-3x^2y^2+3x^2y^2+3x^4y$

$Sum=-2xy^5+3x^4y+3x^2y^2$

Therefore, the sum of the given polynomials is $-2xy^5+3x^4y+3x^2y^2$ . It is a polynomial with degree 6 and leading coefficient -2.
