6 over 8 and or you can do 9 over 12 because you can multiply the numerator and the denominator with any number but what you do to the top has to be the same as the bottom. I multiplied the first one with 2 on the denominator and the numerator. I multiplied the second one with 3 and what you do to the bottom has to be the same as the top
Answer:
-12
Step-by-step explanation:
x-9.37+5.77=1.3x
Answer:
Choice 4.
Step-by-step explanation:
f(g(x))
Replace g(x) with x^2+8 since g(x)=x^2+8.
f(g(x))
f(x^2+8)
Replace old input,x, in f with new input, (x^2+8).
f(g(x))
f(x^2+8)
2(x^2+8)+5
Distribute:
f(g(x))
f(x^2+8)
2(x^2+8)+5
2x^2+16+5
Combine like terms:
f(g(x))
f(x^2+8)
2(x^2+8)+5
2x^2+16+5
2x^2+21
TO find perimeter you add all sides. But to find the totaly of each side, you will divide. So a triangle has 3 sides, so you divide 45 by 3 to get the sides length of:
15 cm each
