Answer:
The answer to your question is:
first test = 72
second test = 88
third test = 89
Step-by-step explanation:
Data
First test = 72 points
Second test = x
Third test = x + 1
Average of the three test = 83
Process
(First test + Second test + Third test) / 3 = 83
( 72 + x + x +1 ) / 3 = 83
73 + 2x = 3(83)
73 + 2x = 249
2x = 249 - 73
2x = 176
x = 176 / 2 = 88 second test
third test = x + 1 = 88 + 1 = 89

Answer:
-22
Step-by-step explanation:
9-31=-22
Solution:
<u>Note that:</u>
- Area = Base x Height
- Perimeter = Sum of all sides
<u>Finding the area of the parallelogram:</u>
- Area = Base x Height
- => Area = 9.2 x 3.8
- => Area = 34.96 cm²
<u>Finding the perimeter of the parallelogram:</u>
- Perimeter = Sum of all sides
- => Perimeter = 2(4.1) + 2(9.2)
- => Perimeter = 26.6 cm
Correct option is D.
For this case, the dividend is given by:

We note that the following numbers:
2, 10, 1, 5
They are the coefficients of the polynomial and they are in the upper part of the division.
The number -5 is the opposite value of the divisor constant.
Therefore, the divisor is given by:
x + 5
Answer:
The divisor is:
x + 5
