What is the sum of the polynomials?

Nadya [2.5K]

For this case we have the following polynomials:

$-x ^ 2 + 9\\-3x ^ 2 - 11x + 4$

Adding the polynomials we have:

$(-x ^ 2 + 9) + (-3x ^ 2 - 11x + 4)$

Rewriting we have:

$x ^ 2 (-1-3) - 11x + (9 + 4)$

Therefore, the result of the sum is:

$-4x ^ 2 - 11x + 13$

Answer:

the sum of the polynomials is:

$-4x ^ 2 - 11x + 13$

A rectangle has a height of 3 cm and width of 5cm. A proportional rectangle has a height of 12cm. What would be the width?

Schach [20]

The ratio will be same

Let width be x

$\\ \sf\longmapsto \dfrac{3}{5}=\dfrac{12}{x}$

$\\ \sf\longmapsto 3x=5(12)$

$\\ \sf\longmapsto 3x=60$

$\\ \sf\longmapsto x=\dfrac{60}{3}$

$\\ \sf\longmapsto x=20cm$
