Explanation:
For any convex polygon, the sum of the exterior angles is always 360 degrees.
The exterior angles (5x+12), (10x-37) and (9x+1) add to 360. Use this to solve for x.
(5x+12)+(10x-37)+(9x+1) = 360
(5x+10x+9x) + (12-37+1) = 360
24x-24 = 360
24x = 360+24
24x = 384
x = 384/24
x = 16
The expression 10x-37 is then
10x-37 = 10*16-37 = 160-37 = 123
which is the measure of the exterior angle adjacent to angle BCA
The last step is to subtract this from 180 to get angle BCA itself
angle BCA = 180 - 123 = 57
Answer:
61728394.5
Step-by-step explanation:
Using order of operations, you can either perform the multiplication first or the division first.
123,456,789 × 2 / 4 =
123,456,789 / 2 =
61728394.5
Al factorizar la expresión dada obtenemos que es igual a x²*(5 - x)*(5 + 5)
Por propiedad de los números reales: tenemos que para a y b dos números reales, se cumple que:
(a² - b²) = (a + b)*(a - b)
Por lo tanto como tenemos: - x⁴ + 25x², ordenamos:
- x⁴ + 25x² = (25*x² - x⁴ = ((5x)² - (x²)²)
Usando la propiedad dada inicialmente: obtenemos que:
((5x)² - (x²)²) = (5x - x²)*(5x + x²)
Sacamos de cada término un factor común "x":
x*(5 - x)*x*(5 + x) = x²*(5 - x)*(5 + 5)

Answer: The answer would be $28.75
Step-by-step explanation: You would first wanna see how much one bag of dog food costs by dividing 34.50 by 6. Then you can muiltiply how much one bag of dog food costs by 5 to see how much Amelia would spend.
1,000,000 x 1.08 = $1,080,000
12month x 30 years = 360 months
1,080,000/360 = $3000 per month
