I think it might be 43° because since the line is going through the middle, it would be 180-47-90=43 (the 90 came from the right angle)
hope this helps! :)
Hello, There are endless expressions. Since, you multiply this fraction by a costant k / k
If k = 2
Then,
(5/9) = ( 5/9) × ( k / k)
= (5/9) × ( 2/2)
= (5 × 2 / 9×2)
= 10 / 18
________________
The only restriction for k is zero and the infinite. Because there is no "0/0" and "infinito/ infinito" at math.
Answer:
x8 + 1
Step-by-step explanation:
(x + 2)(x - 4)
= x^2 + 2x - 4x - 8
= x^2 - 2x - 8
