Answer:
Step-by-step explanation:
4/9 to 20/x
cross multiply and divide to get your answer
4 20
9 x
4x=180
x=45
Answer: I think the answer is B
Step-By-Step Explination:
First you find out what x is by doing 42 multiplying it by 0.1 witch equals 4.2 gallons per mile
Next you figure out what y is by doing 4.2y (witch is 4.2 times y)
F(x) = 3x + 9
g(x) = 5x²
(f + g)(x) = (3x + 9) + 5x²
(f + g)(x) = 3x + 9 + 5x²
(f + g)(x) = 5x² + 3x + 9
Answer:
c.sss because they have the same angles and triangles
