Answer:
Step-by-step explanation:
Given that,
Speed of a car, v = 120 km/s
It takes 120 minutes
v = 120000 m/s
t = 7200 s
We need to find the distance covered. Speed is given by :
v = distance/time
So, the distance covered is 
.
Multiplication and division are inverse operations.
If you start with a number and divide it and multiply it by the same number (not zero), you get the original number back.
Since you want to undo a division by 7, you must multiply by 7.
Answer: A. Multiplying by 7
Answer:
y=2(x+2)(x+3)
Step-by-step explanation:
First, we need to factor the right side:
y=2(x^2+5x+6)
Now, we can have an incomplete equation like this:
y=2(x+_)(x+_)
In the blanks, we need to fill out numbers that add to be 5 and multiply to be 6. What are factors of 6? 6 and 1, 2 and 3. Do 6 and 1 add to be 5? No. Do 2 and 3 add to be 5? Yes!
So, our factored form is
y=2(x+2)(x+3)

$28.35 because if she earns 2.1% interest yearly than she will earn 3.15% for 1 1/2 years
multiply 0.0315 by 900 and you will get 28.35</span>
