Answer:

108 - 30x - 116x² - 18x³

Step-by-step explanation:

We have to get the value of - (2x + 12) (9x² + 4x - 9)

Now, using the distributive property of multiplication we get

- (2x + 12) (9x² + 4x - 9)

= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]

= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]

= -[18x³ + 116x² + 30x - 108]

= 108 - 30x - 116x² - 18x³ (Answer)

Find the angle measurements and side lengths for the triangle below
rewona [7]

Answer:

Step-by-step explanation:

Sin(A) = 5/7

Sin(A) = 0.7143

A = sin-1(0.7143

A = 45.58

B = 180 - 45.58 - 90

B =  44.43

C = 90

c = 7

a = 5

b^2 = c^2 - a^2

b^2 = 7^2 - 5^2

b^2 = 49 - 25

b^2 = 24

b = 4.899
