In this case all you do is add all the numbers, answer is 100
Answer:
Get a calculator
Step-by-step explanation:
Most of the time for simple math like multiplying 2 digits, it is easiest if you just get a calculator. It saves a lot of time.
If you can't get a calculator then i recommend memorizing some common equations.
For example 10*15= 150
so that if you get 12*15=?, you can easily just add two extra 15's to your answer of 150.
15+15 is 30, and 30+150(from 10*15)=180.
Therefore 12*15=180.

Step-by-step explanation:
A function is given to us and we need to tell which graph represents the given function. The function given to us is,
Let's find out at which points do the graph Intersects x axis / finding the roots. For that substitute f(x) = 0 , we have ,
Equate each factor by 0 ,
Therefore the graph will intersect x axis at x is equal to -1 and x is equal to -3 .
On looking at the given graphs in the options the second graph intersects x axis at -1 and -3 .
<u>Hence</u><u> </u><u>the </u><u>second</u><u> </u><u>option</u><u> </u><u>is </u><u>correct</u><u> </u><u>.</u><u> </u>

Answer:
666.6667 feet²
Step-by-step explanation:
So.
Since the scale is 1 : 20, we can do 4 x 20 and 5 x 20, Which is 80 and 100.
Find area: 80 x 100 = 8000 we can just add 2 zeros to 80 since it's multiplying by 100.
So it's 8000in²
Then we do 8000 in to feet.
Which is ≈ 666.6667feet
btw it asked for feet so we give them FEET
