Find the area of the rectangle.
2x + 4
4x - 2
Answer:
8x² + 12x – 8
Step-by-step explanation:
From the question given above, the following were obtained:
Length (L) = 2x + 4
Breadth (B) = 4x – 2
Area (A) =..?
The area of a rectangle is given by:
Area (A) = Length (L) × Breadth (B)
A = L × B
Thus with the above formula, we can obtain the area of the rectangle as follow:
Length (L) = 2x + 4
Breadth (B) = 4x – 2
Area (A) =..?
A = L × B
A = (2x + 4) (4x – 2)
Expand
A = 2x(4x – 2) + 4(4x – 2)
A = 8x² – 4x + 16x – 8
A = 8x² + 12x – 8
Therefore, the area of the rectangle is 8x² + 12x – 8
A store sells bouquets of fruits for $10 a bouquet. The daily cost to produce x bouquets of fruits is defined by the function f(x) = – x 4 + 3x 3 + 5x 2 + 20x + 1.
Answer:
5 or C
Step-by-step explanation:
when you plug in 5, you get -24 as the cost. Then you take that number with the amount of money you make selling 5 flowers and that would be $50 since they are $10/per bouquet. Then when you subtract you get a positive profit of $26.
Answer:
5
Step-by-step explanation:
For profit to be had, the selling price (represented by $10x, x being number of bouquets sold) must be greater than the cost to produce (here, -x^4 + 3x^3 + 5x^2 + 20x +1).
Set up an inequality such that 10x is greater than the cost to produce.
10x > -x^4 + 3x^3 + 5x^2 + 20x + 1
-Solving the inequality by subtracting 10x from both sides, we have:
0 > -x^4 + 3x^3 + 5x^2 + 10x + 1
-Using a graphing calculator, (the one they give you on Edgenuity) graph the new function and look for where the graph is below the x axis. (y is less than 0)
Looking at the graph, we see that when x is greater than 0, (you can't sell a negative amount of bouquets) y is greater than 0 up until x = 4.579. After 4.579, the y values become negative. (what we want to be looking at according to the inequality.)
You can't sell 4.579 bouquets, and even if you could, you'd be breaking even, with y=0. The answer isn't 4, because according to the graph and inequality, y would be greater than 0 (making the inequality false). Because of this, we have to find the next whole positive number that would make the inequality true, and that is 5.

four times the sum of a number and ten is 60. find the number.
Answer choices:
A. 4
B. 5
C. 6
D. 7
Answer:
B. 5Step-by-step explanation:
x - the number
x + 10 - the sum of the number and ten
4×(x + 10) - four times the sum of the number and ten
4×(x + 10) = 60
÷4 ÷4
x + 10 = 15

if LM=3x-9 and MN=x+1, find LN
Answer:
LN=12
Step-by-step explanation:
3x-9=x+1 add 9 to both sides
3x=x+10 subtract 1x on both sides
2x=10 divide by 2
x=5
3(5)=15-9=6

Jasmine is thinking about buying a car and is comparing two vehicles. One gets 13 miles to the gallon (mpg) and the other agents 26 miles to the gallon. Assuming that she drives 5,000 miles a year, how much money would she save by buying the more fuel efficient car if gas is $3 a gallon?
Answer:
$576.93
Step-by-step explanation:
Car A
13 miles to the gallon (mpg)
13 miles = 1 gallon
Car B
26 miles to the gallon
26 miles = 1 gallon
Car B is more fuel efficient than car A
1 gallon = $3
Assuming that she drives 5,000 miles a year
Cost of buying Car A
5000 miles / 13 miles × $3
= 384.62 × 3
= $1,153.86
Cost of buying car B
5000 miles / 26 miles × $3
= 192.31 × 3
= $576.93
Car A - car B
= $1,153.86 - $576.93
= $576.93
Jasmine will save $576.93 by buying the more fuel efficient car if gas is $3 per gallon
If John pays $144 for 9 pounds of pears, how much is each pound
Answer:
$16 per pound
Step-by-step explanation:
We want to find the price per pound.
Therefore, we must divide the cost by the pounds.
[tex]\frac{cost}{pounds}[/tex]
We know it costs $144 for 9 pounds of pears. Therefore, $144 is the cost and there are 9 pounds.
[tex]\frac{\$144}{9 pounds}[/tex]
Divide.
[tex]\$16 /pound[/tex]
It costs $16 for each pound of pears.

A storage unit has the dimensions shown. What number of
12ft x 12ft x 12ft cardboard boxes would it take to completely
fill this storage unit?
6 ft
7+ A
44 ft
Answer:
the number of boxes that would take fill
the storage completely is 60 boxes.
Step-by-step explanation:
given:
A storage unit has the dimensions 6 ft. x 7 1/2 ft. x 4 1/2 ft.
find:
What number of
1 1/2 ft. x 1 1/2 ft. x 1 1/2 ft. cardboard boxes would it take to completely
fill this storage unit?
Volume of a storage unit = 6 x 7.5 x 4.5
Volume of a storage unit = 202.5 ft³
Volume of a cardboard box = 1.5 x 1.5 x 1.5
Volume of a cardboard box = 3.38 ft³
to get the number of cardboard boxes to fill in the storage unit,
Number of boxes = 202.5 ft³
3.38 ft³
Number of boxes = 60
therefore,
the number of boxes that would take fill the storage completely is 60 boxes.
