Then you have to multiply how many sides there are by how long they are.
In this case the equation would be:
12 x 1 = 12 so, the perimeter is 12 square feet.

A type of fish for your aquarium costs $4 each. You can spend at most $36. How many fish can you buy? Write an inequality to model the problem? Then solve the inequality to find the number of fish.
Answers
Answer:
9 fish
Step-by-step explanation:
If each fish costs 4 dollars, and we can spend at most 36 dollars, we can find out that we can buy 9 fish by dividing 36/4, which gives you the answer of 9.
We can model this problem by doing
4x = 36
Divide by 4 on both sides to isolate the x
x = 9
Answer:
4x ≤ 36
x ≤ 9
9 fish maximum

A rectangular poster is 3times as long as it is wide. The perimeter is 24 inches. What are the lengths and widths?
Answers
Answer:
Length: 9 inches per side
Width: 3 inches per side
Step-by-step explanation:
Perimeter = 2*width + 2*length
Perimeter = (2 x W) + (2 x 3W) = 8W.
Since we know P = 24, it is also = 8W
With 24=8W, divide each side by 8, and W = 3.
So if W=3, the width is 3 inches, and the length is 3W, or 3x3 which is 9.

Answer:
The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. To find the slope, use the distance formula. The distance formula is Y2-Y1/X2-X1. You can use any two points on the graph but I will use (0,4) and (3,6).
6-4/3-0
2/3
The slope is 2/3. To find the y-intercept, look at the graph and find the where the line crosses the y-axis. The y-intercept in 4. So, the equation of this line is y=2/3x+4.

Answer:
[tex]y=\boxed{\dfrac{2}{3}}\:\:x+\boxed{4}[/tex]
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]y = mx + b[/tex]
where:
m is the slopeb is the y-interceptTo find the slope of the given line, define two points on the line:
[tex](x_1,y_1)=(-6,0)[/tex][tex](x_2,y_2)=(0,4)[/tex]Substitute the two defined points into the slope formula and solve for m:
[tex]\implies \textsf{slope}\:(m)=\dfrac{4-0}{0-(-6)}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]
The y-intercept is y-value of the point at which the lines crosses the y-axis. From inspection of the graph, the y-intercept is 4.
Therefore, substitute the found slope and y-intercept into the slope-intercept formula to create the equation of the given line:
[tex]\implies y=\dfrac{2}{3}x+4[/tex]

ALGEBRAIC PROOF!!!! PLS HELP!!! The area of a rectangular blanket is 20 square feet. The blanket's length is (2x + 1) ft and the blanket's width is 2x ft. find the dimensions of the blanket. provide justification for each step.
Answers
Answer:
Length: 5 ft; width: 4 ft.
Step-by-step explanation:
A = LW formula for area of rectangle
(2x + 1)(2x) = 20 substitute length, width, and area into formula
4x² + 2x - 20 = 0 use the distributive property to multiply out left side
2x² + x - 10 = 0 divide both sides of equation by 2
(2x + 5)(x - 2) = 0 factor out trinomial
2x + 5 = 0 or x - 2 = 0 use zero product rule to solve for x
2x = -5 or x = 2 subtract 5 from both sides; add 2 to both sides
x = -5/2 or x = 2
We discard x = -5/2 since it would give negative length and width, and the length and width cannot be negative.
Length: 2x + 1 = 2(2) + 1 = 5
Width: 2x = 2(2) = 4
Length: 5 ft; width: 4 ft.

What is the least common denominator? LCD in math
The LCD of 1/2 and 1/3 is 6, because LCM(2, 3) = 6;
Knowing the LCD, you can find equivalent fractions to yours 1/2 and 1/3, with the denominator equal to found LCD:
Answer:
12.
Step-by-step explanation:
One way to find the LCD is from the prime factors:
4 = 2*2
6 = 2*3
One '2' occurs in both sets, so we only include one of these 2's, so the LCD
= 2*2*3
= 12.

Write an explicit formula for the sequence

Step-by-step explanation:
The explicit formula for an arithmetic sequence is
[tex]u_{n}[/tex] = u₁ + (n - 1)d
where u₁ is the first term and d the common difference
To find u₁ use the given recursive formula
u₁ = u₀ - 5.6 = 3.2 - 5.6 = - 2.4
from the recursive formula d = - 5.6 , then explicit formula is
[tex]u_{n}[/tex] = - 2.4 - 5.6(n - 1) = - 2.4 - 5.6n + 5.6 = - 5.6n + 3.2
