Answer:
x = 20
B = 92
C = 40
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
A+B+C = 180
48+6x-28+2x = 180
Combine like terms
20+8x =180
Subtract 20 from each side
20+8x-20 = 180-20
8x = 160
Divide each side by 8
8x/8 = 160/8
x = 20
Then we need to find angle B
B = 6x-28 = 6(20)-28 = 120-28 =92
Then we need to find angle C
C = 2x = 2(20) = 40
Its A because Sue ran 7 miles more and you’re supposed to add the amount of miles Due ran not subtract them.
Answer:
a) f g(x) = x³ - 5 x² + x -5
b) g(f(x) = x³ - 5 x² + x -5
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that f(x) = x² + 1 and g(x) = x-5
a)
f(g(x)) = f(x-5) = (x-5)²+1 = x² - 10x +25 +1 = x² - 10 x +26
<u><em>Step(ii):-</em></u>
a) f g(x) = f(x) g(x) = (x² + 1 )(x-5) = x³ - 5 x² + x -5
b) g(f(x) = g(x) f(x) = (x-5) (x²+1) = x³ - 5 x² + x -5
