You can tell if two fractions are proportional by cross multiplying the fractions. If the fractions are equivalent, then they are proportional. If they are not equivalent, they are not proportional.
To find the area of the larger figure, let's multiply the length by the width.
9 ft * 4 ft = 36ft^2
Let's do the same thing with the smaller figure.
3 ft * 4 ft = 12ft^2
Let's add the area of both figures together.
36ft^2 + 12ft^2 = 48ft^2
Answer: I need to find the additive inverse of the number being su tracked. That number is -9.6. The additive inverse of -9.6 is 9.6.
Step-by-step explanation:
Answer: 12.37ft

Step-by-step explanation:
The formula to find the missing side of a triangle is a^2 + b^2 = c^2
so all you have to do is put 3 and 12
3^2 + 12^2 = c^2
9 + 144 = c^2
153 = c^2
√153 = 12.37
