Which expression represents the perimeter of the rectangle shown below
Answer:
D. 2x² + 10x - 2
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = x² + 3x - 2
Width = 2x + 1
Perimeter = 2(x² + 3x - 2 + 2x + 1)
Perimeter = 2(x² + 5x - 1)
Perimeter = 2(x²) + 2(5x) - 2(1)
Perimeter = 2x² + 10x - 2
factor completely

This one is actually pretty easy. We will divide 136 by 16 which will convert the 136 oz into single pounds. After dividing, we get 8.5 pounds.
Answer:
8.5 pounds
Step-by-step explanation:
you devide 136 by 16 and you get the total weight in pounds which in this case would be 8 1/2 or 8.5

Regression Project: Find the Profit Model
Annual Widget Production x (widgets) Annual Total Cost c($)

20 1105
30 1523
40 2150
50 2603
60 3121
70 3672
80 4103
90 4601
100 5214
Recall that profit can be computed in terms of revenue and cost. Assume that the annual widget sales match the annual widget demand and annual widget production. Construct a model for profit using the models for revenue and cost that you found in the Revenue and Cost sections. Find the model for profit P ( x ), where P ( x ) is the total annual profit in dollars for x widgets sold, and write it as P ( x ) = a x 2 + b x + c. Note: You are using the fact that P ( x ) = R ( x ) − C ( x ), not creating a table of data.
value of a. -0.956
value of b. 106.2
value of c. ???????????????????? It is not 0, 73.4, 124.2, 104.87, 157, 50.8 I've tried all of these
Answer:
value of c is -73.4
Step-by-step explanation:
When you subtract revenue from cost the Profit model becomes
P(x)= -0.956x^2 + 106.2x - 73.4

compare the fraction 3/5 to 1/2
Answer:
1 / 2 is smaller than 3 / 5.
Step-by-step explanation:
Compare 1/2 and 3/5. 1 / 2 is smaller than 3 / 5. Steps for comparing fractions. Find the least common denominator or LCM of the two denominators: LCM of 2 and 5 is 10; For the 1st fraction, since 2 × 5 = 10, 1 / 2 = 1 × 5 / 2 × 5 = 5 / 10; Likewise, for the 2nd fraction, since 5 × 2 = 10, 3 / 5 = 3 × 2 / 5 × 2 = 6 / 10 Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

A = nr^2. find the value of A when n = 3.142 and r =5
Answer:
A = 78.55
Step-by-step explanation:
A = nr^2
substitute the n and r values
A = 3.142(5)^2
Use PEMDAS
Parenthesis Exponents Multiply Divide Add Subtract
so the first step is exponents
5^2 is 25
A = 3.142(25)
Multiply
A = 78.55
