Answer:
A. 12 centimeters B. 4 centimeters C. 20 centimeters
Step-by-step explanation:
To find area you need to do the Height time the Length.
For A it is 3x4
For B it is 4x1
And for C it is 4x5
You get this equation by multiplying the amount of squares that the Height and Length measured!
Hope this helped!

The algebraic expression for the mathematical statement given as 4 more than the difference of 12 and a number j is 4 + 12 - j
<h3>How to determine the arithmetic expression?</h3>
The mathematical statement is given as:
4 more than the difference of 12 and a number j
4 more than means 4 +.
So, we have:
4 + the difference of 12 and a number j
the difference of 12 and a number j means 12 - j
So, we have
4 + 12 - j
Hence, the algebraic expression for the mathematical statement given as 4 more than the difference of 12 and a number j is 4 + 12 - j

Answer:
33.3%
Step-by-step explanation:
The number of people that must be fed has increased from 4 to 6, so is 6/4 = 3/2 as many as planned.
Assuming the additional people eat the food at the same rate as the original people, the time and number of people are assumed to be inversely proportional. That is, the time the food will last is 2/3 of the originally expected time. It has decreased by 1/3 × 100% = 33.3%.
___
If you like, you can count rations. For four people for 12 days, at 3 rations per person per day, a total of 144 rations are needed. When the number of people becomes 6, the number of days that will last is ,,,
(144 rations)/(6 persons)/(3 rations/person/day) = 8 days
The percentage change in trip days is ...
(8 -12)/12 × 100% = -4/12 × 100% = -33.3% . . . a decrease of 33.3%
When solving for a coefficient the variable to look for is 1
