A model rocket is built to scale is 3 cm = 5 m. If the model is 9.4 cm tall, how tall is the actual rocket?
SashulF [63]
Since there may be an easier way, you can find how many centimeters there may be for one meter by dividing both sides (3 cm = 5 m ) by 5.
3 \div 5 = .6 \\ 5 \div 5 = 1
So, .6 cm= 1 m
This will make it easy to divide to find the actual ticket size.
You have to find how many .6 there are in 9.4 by dividing:
9.4 \div .6 = 15 \frac{2}{3}
The rocket would be
15 \frac{2}{3}
m tall.

X + 1 is a factor of x^5 + 4x^3 - 17x + 12. True or False
Georgia [21]
False.

If (x+1) is a factor of the polynomial, the polynomial must be divisible by (x+1).

In other words, when you divide the polynomial by (x+1), the remainder should be 0.

In this case, however, the remainder is 24.
