A rectangle has a width represented by the expression-2x+20. The length of the rectangle is 6 more than twice the width. Which expression represents the area of the rectangle?
The perimeter of a rectangle is given by:
[tex]\boxed{\bold{Perimeter = 2 (length + width)}}[/tex]
In the problem we have these data:
Length = a Width = -2x + 20 Perimeter = 6 + 2 (-2x + 20)
We replace the data in the equation of the perimeter:
6 + 2 (-2x + 20) = 2 (a - 2x + 20)
We apply distributive property:
6 - 4x + 40 = 2a - 4x + 40
6 = 2a
6 ÷ 2 = a
3 = a
⇒ Length = 3
The area of the rectangle is given by:
[tex]\boxed{\bold{Area = 2 (length + width)}}[/tex]
We have these data:
Length = 3 Width = -2x + 20
We replace the data in the equation of the area:
Area = (3) (- 2x + 20)
We apply the distributive property and obtain:
Area = -6x + 60
The expression representing the area of the rectangle will be -6x + 60
I hope I've helped!

Mark uses 3 1/8 pounds of seed to fill the birdfeeders in his backyard, but he only has 1 1/2 pounds of seeds.
Part A
How much seed does he need to buy?
Answer:
1 5/8 pound.
Step-by-step explanation:
Convert 1/2 into 1/8's.
1/2 = 4/8.
We now have 1 4/8.
Subtract that from 3 1/8.
3 1/8
- 1 4/8
-----------
1 5/8
Your answer is 1 5/8 pound.
Hope this helps. Have a nice day.

Ariane feeds her kitten kkk grams of food 222 times in the morning and 222 times in the evening. She feeds her dog ddd grams of food 111 time in the morning and 111 time in the evening.
Which expressions can we use to describe how many grams of food Ariane feeds her animals per day?
Choose 2 answers:
Answer:
The required expression is,
4k + 2d
Step-by-step explanation:
Given,
She feeds her kitten k gram of food,
She feeds 2 times in the morning,
⇒ Food fed in morning = 2k,
Also, she feeds 2 times in the evening,
⇒ Food fed in evening = 2k,
So, the total food she gives to her kitten = 2k + 2k = 4k,
Now, She feeds her dog d gram of food,
She feeds 1 times in the morning,
⇒ Food fed in morning = d,
Also, she feeds 2 times in the evening,
⇒ Food fed in evening = d,
So, the total food she gives to her dog = d + d = 2d,
Hence, the total food she feeds to her animal in a day = 4 k + 2 d

Miguel recently sold some farmland and bought a new plot that consists of 968 acres. Miguel calculates that this is 20% less acreage than he used to own. What was the acreage of the old land?
Answer:
1210 acres
Step-by-step explanation:
Given data
let the old farmland be x acres
new farmland = 968 acres
therefore
let us find 20% of the old farmland
=20/100x
=0.2x
Hence
968+0.2x=x
collect like terms
968=x-0.2x
968=0.8x
x= 968/0.8
x=1210 acres

Find the area of the shaded region.
Answer:
B. x^2-10
Step-by-step explanation:
Your are trying to find the shaded region
You can see that the x by x square would be "full" if not for the 2 by 5 chunk that has been taken out of it
Therefore you can find the area by subtracting the 2 by 10 "chunk" out of the total area of the x by x square
Equation:
(x*x)-(2*5)
x^2-10
The answer is B
Find the area of the polygon.
Answer: use formulas for area of square/triangle
Step-by-step explanation:
1st one is a rhombus so use A= BH
which is 5x4 = 20
2nd one is a kite
i assume you have not learnt the formula for kites so u can use triangles (A=1/2BH)
triangle CBA: 1/2 x (6+6)(2) = 12
triangle ACD: 1/2 x (6+6)(10)= 60
area = 12 + 60 = 72
Four equal triangles inside a polygon, so we have to find an area of one triangle and multiply that area with four since there are four triangles in total.
base is 5, height is 4. area of triangle formula: A = (bh) / 2 = (5x4) / 2 = 20 / 2 = 1010 x 4 = 40 (b/c there are four equal triangles)40 square units is the area of green/second polygon________________________________________________________
teal/second polygon:Two equal triangles and another two (different) equal triangles, so we have to find an area of a smaller triangle and multiply that area with two since there are two equal smaller triangles.
Then we have to find an area of a larger triangle and multiply that area with two since there are two larger equal triangles.
(smaller triangle)base is 6, height is 2. area of triangle formula: A = (bh) / 2 = (6x2) / 2 = 12 / 2 = 66 x 2 = 12 (b/c there are two equal smaller triangles)12 square units of the area of two equal smaller triangles (so we're not done yet!)------------------------------------------------------------
(larger triangle)base is 10, height is 6. area of triangle formula: A = (bh) / 2 = (10x6) / 2 = 60 / 2 = 3030 x 2 = 60 (b/c there are two equal larger triangles)60 square units of the area of two equal larger triangles12 + 60 = 72
72 square units is the area of teal/second polygon.

Answer:
y = x - 10
Step-by-step explanation:
(2,-8) and (6,-4)
m=(y2-y1)/(x2-x1)
m= (-4 + 8)/(6-2)
m= 4/4
m=1
y - y1 = m(x - x1)

Points A and B have opposite x-coordinates but the same y-coordinates. On a coordinate plane, point A is 2 units to the left and 3 units up. Point B is 2 units to the right and 3 units up. How many units away are each of the points from the y-axis? 2 3 4 5
Answer: 5
Step-by-step explanation: If you take minus 2 and take it to 0 then add 3 you get 5
The points A and B are 2 units away from the y-axis.
What is Cartesian coordinates system?"It is used to specify the location of a point in two-dimensional plane or three-dimensional space.""The cartesian plane is a two-dimensional coordinate plane, formed by the intersection of the x-axis and y-axis."What is the distance of point from Y-axis?"The distance of a point from the Y-axis is its x-coordinate."
For given question,
Points A and B have opposite x-coordinates but the same y-coordinates.
Point A is 2 units to the left and 3 units up.
So the point A has coordinates (-2, 3)
Point B is 2 units to the right and 3 units up.
So the point B has coordinates (2, 3)
We know that the distance of a point from the y - axis is its x-coordinate.
So, the distance of point A from the y-axis is |-2| = 2 units
And the distance of point B from the y-axis is 2 units
Therefore, points A and B are 2 units away from the y-axis.
