(5x - 7) * (9x^2 - 4x - 8)

1.) Try using the FOIL method (First*first, outside*outside, inside*inside, last*last):

(5x)(9x^2) + (5x)(-4x) + (5x)(-8) + (-7)(9x^2)

2.) Multiply the bases and add the exponents:

45x^3 - 20x^2 - 40x - 63^2 + 28x + 56

3.) Look for the variables without exponents:

-40x + 28x = 28x

45^3 - 83x^2 - 12x + 56

Answer:

56.7°

Step-by-step explanation:

We solve this above question using the Trigonometric function of Sine

sin x = Opposite side/Hypotenuse

Opposite = 66mm

Hypotenuse = 79 mm

sin x = 66/79

x =arc sin(66/79)

x = arcsin(0.8354430379746836)

x = 56.661998553°

Approximately = 56.7°

What is 4/9 - 2/15 in simplest form
Georgia [21]
To subtract 2 fraction we have to make common denominator.
\frac{4}{9} - \frac{2}{15} = \frac{4*5}{9*5}- \frac{2*3}{15*3}  = \frac{20}{45}- \frac{6}{45} = \frac{20-6}{45}= \frac{14}{45} - its the simpest form
