Answer;
4 small rectangles
That is; 20 by 80, 20 by 3, 7 by 80, and 7 by 3.
Explanation;
We have; 27 by 83
We can decompose 27 into 10s and 1s to get; 20 + 7 , and
also decompose, 83 into 10s and 1s to get; 80 + 3;
But we know area is given by length times width, thus;
we have rectangles; 20 × 80, 20 × 3, 7 × 80 and 7 × 3
-The total area will be given by the sum of the area of the four triangles that is equivalent to 83 × 27.

Greg's daughter will have $533 in her piggy bank in a year
The money in the piggy bank would increase everyday by the amount put in it. There are seven days in a week. If he puts $0.75 everyday apart from on Sundays when we puts $5.75, the amount that would be in the piggy bank in a week is the sum of the money deposited each day.
Total amount in a week = total amount deposited from Monday to Saturday + amount deposited on Sunday
- Amount that Greg puts in 6 days : ($0.75 x 6) = $4.50
- Amount deposited on Sunday = $5.75
- Total amount = $5.75 + $4.50 = $10.25
The total amount Greg's daughter would have in a year is a function of the number of weeks in year and the total amount saved in a week
Total amount in a year = number of weeks in year x the total amount saved in a week
- Number of weeks in year = 52
- The total amount saved in a week = $10.25
$10.25 x 52 = $533
In order to determine how much Greg's daughter would have in a year, first determine how much she would have in a week. Multiply this amount by the number of weeks in a year

Answer:
12x⁴ - 15x³ + 18x²
Step-by-step explanation:
1. distribute -3x²
-3x² • 5x = -15x³
-3x² • -4x² = 12x⁴
-3x² • -6 = 18x²
2. combine terms and put in descending order (standard form)
12x⁴ - 15x³ + 18x²
Answer:
s = 19.7
Step-by-step explanation:
First we need to calculate the mean x' of the sample as:
We sum all the scores and divide them by the number of scores.
Then, the standard deviation s is calculated as:
We square every score less the mean, sum every value, then divide that by the number of scores less 1 and finally, we calculate the square root.
So, the standard deviation of the sample is 19.7
