Answer:

12y² + 16xy -12x -29y + 15

Step-by-step explanation:

(4y - 3)(2x · 2 + (3y - 5))

multiply 2x with 2

(4y - 3)(4x + 3y - 5)

distribute (or foil) 4y - 3 into 4x + 3y -5

16xy + 12y² - 20y - 12x - 9y + 15

combine like terms

16xy + 12y² - 29y - 12x + 15

rearrange to the correct order

12y² + 16xy -12x -29y + 15

In AOPQ, o = 700 cm, p = 840 cm and q=620 cm. Find the measure of _P to the<br> nearest degree

Westkost [7]

Given:

In triangle OPQ, o = 700 cm, p = 840 cm and q=620 cm.

To find:

The measure of angle P.

Solution:

According to the Law of Cosines:

$\cos A=\dfrac{b^2+c^2-a^2}{2bc}$

Using Law of Cosines in triangle OPQ, we get

$\cos P=\dfrac{o^2+q^2-p^2}{2oq}$

$\cos P=\dfrac{(700)^2+(620)^2-(840)^2}{2(700)(620)}$

$\cos P=\dfrac{490000+384400-705600}{868000}$

$\cos P=\dfrac{168800}{868000}$

On further simplification, we get

$\cos P=0.19447$

$P=\cos^{-1}(0.19447)$

$P=78.786236$

$P\approx 79$

Therefore, the measure of angle P is 79 degrees.
