To compare fractions, you need a common denominator.
6 goes into 18 three times. If we multiply (5/6) by 3 on top and bottom you get
Now we can compare numerators, since 15 > 13
Area of the bottom triangle = 1/2 x 10 x 8.7 = 43.5 cm²
Area of the 3 rectangles = 3(10 x 6) = 180 cm²
Area of the top triangle = 3 (1/2 x10 x 4) = 60 cm²
Total surface are = 43.5 + 180 + 60 = 283.5 cm²
Answer: 283.5 cm²

<h2>
</h2>
Step-by-step explanation:
To find (f ∘ g)(x) , substitute g(x) into f(x). That is for every x in f (x) replace it with g (x)
That's

Answer:
3 ; 4/3
Step-by-step explanation:
x + 4(1/x) = 13/3
x + 4/x = 13/3
x^2 -13/3x + 4 = 0
3x^2 - 13x + 12 = 0
Δ = 169 - 144 = 25
x1 = (13 + 5)/6 = 3
x2 = (13-5)/6 = 4/3
