Answer:
A) 3cm and 1.75cm
Step-by-step explanation:
To determine whether or not these are proportional, take the two side lengths that are given and create a ratio. 6cm:3.5cm. I suggest writing this in fraction form to better see the equivalency. If you divide both 6cm and 3.5 cm by 2, you create an equivalent ratio of 3 cm:1.75cm. This is answer A. There is another correct answer too! If you take 6cm:3.5cm and multiple both by 1.5, it will create an equivalent ratio of 9cm:5.25 cm (answer choice E), just in a different order.
Answer:
f = - 5
Step-by-step explanation:
9(f+3) = -18
9f + 27 = - 18
9f = - 18 - 27
9f = - 45
f = - 45 : 9
f = - 5
Answer:
C) f(3) = 111
Step-by-step explanation:
f(x) = 3x^3 + 8x^2 – 10x – 12
Let x=3
f(3) = 3(3)^3 + 8(3)^2 – 10(3) – 12
=3*27+8(9) -30-12
=81+72-30-12
=111
