Answer:
315 sq. in
Step-by-step explanation:
15 * 21 = 315
To find the distance between 2 numbers you must take the absolute value of the difference
|90-(-20)|
|110|
110
110 degrees celsius
Y = m x + b , where m is the slope. The slope is the rise over the run or the change in x ( rooms cleaned ) over the change in y ( cost ).
125 = m * 1 + b
175 = m * 2 + b
-----------------------
b = 125 - m
175 = 2 m + 125 - m
m = 175 - 125
m = 50 ( the rate of change ), b = 75
The formula is: y = 50 x + 75
It means that the starting cost will be $75 and that for every room cleaned, the cost will rise for $50.
The two-digit number you are looking for is 12.
4 x 3 = 12.
6 x 2 = 12.
This fits your criteria.
Ok so if e=mc squared then the answer= abcd :)
