Answer:
6
Step-by-step explanation:
24 = 2L + 2(6), multiply...
24 = 2L + 12, subtract 12 to both sides...
12 = 2L, divide 2 to both sides to isolate the varibale L
6 = L
Therefroe, L = 6
The length of a rectangle plus its width is 32
cm. The area is 112 square cm. What are the
length and width of the rectangle?
Separate the answers with a comma.
Answer:
l = 28 cm and b = 4 cm
Step-by-step explanation:
Let the length be l and the breadth be b.
ATQ,
l+b = 32
l=32-b ....(1)
Area of rectangle, A = 112 cm²
We need to find the length and width of the rectangle
The formula for the area of a rectangle is given by :
lb = 112 ...(2)
From equation (1) and (2).
(32-b)b = 112
From above equation, b = 4 cm
Put the value of b in equation (1)
l=32-4
= 28 cm
Hence, the length and width of the rectangle is 28 cm and 4 cm.
y'all i need help immediately
Answer:
Option B
Step-by-step explanation:
Don't trust answers teachers don't bother to spell correctly. Plus, finding the 100th term is very easy.
However, the explicit formula will take a long time to use, because it's explicit.
Option C is just wrong. You're supposed to multiply in the recursive formula.
Option D might be correct, but never trust those answers. Teachers do that to trip you up

standard form (ax + by = c) to slope-intercept form (y = mx + b)
5x+7y= -21 (ANSWER?)
Answer:
y=-5/7x-3
Step-by-step explanation:
so, we need the equation to be in y=mx+b form.
The equation right now is 5x+7y=-21 in standard form.
We need to isolate y onto one side
Here's the equation:
5x+7y=-21
subtract 5x from both sides
7y=-5x-21
divide by 7
y=-5/7x-21/7
simplify
y=-5/7x-3
Hope this helps! :)
Find the 22nd term of the sequence described by the
explicit formula:
f(n) = 8 + 3(n - 1)
[tex]\boxed{\boxed{\pink{\bf \leadsto The \ 22nd \ term \ is \ 71. }}}[/tex]
Step-by-step explanation:Given that the nth term of the Arthemetic Sequence is given by :-
[tex]\implies f(n) = 8 + 3(n-1) [/tex]
And we need to find the 22nd term .
So in place of n substitute 22 .
[tex]\bf\implies f(n) = 8 + 3(n-1) \\\\\bf\implies f_{22} = 8 + 3(22-1) \\\\\bf\implies f_{22} = 8 + 3\times 21 \\\\\bf\implies f_{22} = 8 + 63 \\\\\bf\boxed{\bf\implies f_{22} = 71 }[/tex]
Hence the 22nd term is 71 .Which polynomial function has a leading coefficient of3 and roots -4, i, and 2, all with multiplicity 1?

Y=6,7,8,9,10,11,12,13,14
What is the slope? What does it represent?
Given:
X=number of hours
Y=number of tents made
Table of value.
To find:
The slope and its interpretation.
Solution:
Consider any two points from the table, i.e., (0,6) and (1,7).
The slope is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{7-6}{1-0}[/tex]
[tex]m=\dfrac{1}{1}[/tex]
[tex]m=1[/tex]
Therefore, the slope is 1 and it represent that the number of tents made are increasing by 1 units in each hour.

The sales tax in a certain county is 7%. If an item marked at $19.94 is sold within the county, estimate the final cost of the item once tax is included.
Given:
Rate of sales tax = 7%
Marked price of an item = $19.94
To find:
The final cost of the item once tax is included.
Solution:
We have,
Rate of sales tax = 7%
Marked price of an item = $19.94
[tex]\text{Sales tax}=\dfrac{7}{100}\times 19.94[/tex]
[tex]\text{Sales tax}=1.3958[/tex]
Now, final cost of the item once tax is included is
[tex]\text{Final cost}=\text{Marked price}+\text{Sales tax}[/tex]
[tex]\text{Final cost}=19.94+1.3958[/tex]
[tex]\text{Final cost}=21.3358[/tex]
Therefore, the final cost of the item once tax is included is $21.3358.

Ratio of 200m and 1km.
Answer:
the ratio of this one is 0.2\1
Answer:
To calculate the ratio, we should have both quantities in same units, so we can convert the kilometer into meters, knowing that 1 kilometerr are 1000m.
1 * 1000 = 1000m
We know we need to calculate the ratio 200:1000.
We can know divide both quantities by 200 and get...
200/200:1000/200 = 1:5
And now,, we know this ratio is 1:5..

Two of the vertices of a rectangle are (6,1) and (7,1). If the rectangle has a perimeter of 18 units, then what are the coordinates of its other two vertices?
Answer:
(6,9) and (7,9) - assuming the graph only has a single quadrant and the rectangle is vertical
Step-by-step explanation:
We know that the distance between (6,1) and (7,1) is one unit. Because a rectangle has 2 pairs of equal sides, we know that the distance between the 2 missing coordinates is equal to one. We then add these two units. Because the rectangle has a parameter of 18 units, we then have to subtract these 2 units from the total, leaving us with 16 units for both sides. We then divide 16 by 2 because there are 2 sides, leaving us with 8 units for each side. Assuming we are working with a coordinate graph (with only one quadrant instead of 4 on a coordinate plane), and assuming the rectangle is vertical, the missing coordinates should be 8 units above the coordinates you were given. Hope this helps! :)
