HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
l = 14
Step-by-step explanation:
The perimeter of a rectangle is
P =2(l+w)
The width is x-6
w = x-6
The length is 8 units longer than the width
l = w+8
l = x-6+8
l = x+2
We can substitute this into the equation for Perimeter, which is given as 40
40 = 2(x+2 + x-6)
Combine like terms
40 =2 (2x-4)
Divide by 2
40/2 = 2/2 (2x-4)
20 = 2x-4
Add 4 to each side
20+4 =2x-4+4
24 = 2x
Divide by 2
24/2 =2x/2
12=x
We want to know the length
l = x+2
l =12+2
l = 14
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Multiply the length that you have been given by 2
2: Then, subtract the result from the perimeter.
3: You now have the total length for the remaining 2 sides.
4: Width or height is the number divided by 2.

a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans. if you reach in and grab one jellybean, what is the probability that it will be watermelon flavored
help fast pls 7th grade
The probability that it will be watermelon flavored is -
P{E} = 1/5.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans.
We can write the probability as -
P{E} = (20)/(20 + 45 + 30 + 5)
P{E} = 20/100
P{E} = 1/5
Therefore, the probability that it will be watermelon flavored is -
P{E} = 1/5.

A pair of equations is shown below: y = 3x − 5 y = 6x − 8 Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points) Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points) Source StylesNormal
Answer:
Intersect/Solution at (1, -2)
Step-by-step explanation:
Equation 1: y = 3x - 5
Equation 2: y = 6x - 8
Step 1 Mutliply each side of equations one by -2
New Equation 1: -2y = -6x + 10
New Equation 2: y = 6x -8
Add the Equations: -y = +2
Multiply each side by -1 and you'll get that y = -2
Plug in -2 to either equation: -2 = 3x - 5
add 2 to each side 0 = 3x -3
add 3 to each side 3x = 3
divide by 3 and you'll get that x = 1
Part A:The solution of the pair of the equation is,x=1 and y=- -2.
Part B: If the two equations are graphed, at point (1,-2) will the lines representing the two equations intersect.
How to get the slope intercept form of a straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
y = mx +c
A pair of equations is shown below:
y = 3x − 5 -------1
y = 6x − 8 --------2
Substitute the value of y from the equation 1 into equation 2;
3x − 5=6x − 8
3x=-5+8
3x=3
x=1
Put the value of x in the equation 1;
y = 3x − 5 -------1
y=3(1)-5
y=- -2
Hence,the solution of the pair of the equation is,x=1 and y=- -2 and at point (1,-2) will the lines representing the two equations intersect.

Just saying that there are links people post that scam you and this is requird by Brainly
Step-by-step explanation:
The table is completed below.
We can say that the relationship between the scale factor and the area of scaled copies is proportional.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
Using the formula for the area of a triangle:
Area = 1/2 x base x height
With a base of 3cm and height of 2cm, the area of the original triangle is:
Area = 1/2 x 3cm x 2cm = 3cm²
To find the area of the scaled triangles, we can use the scale factor to determine the corresponding dimensions, and then calculate the area using the same formula.
Scale factor Corresponding dimensions Area
1 3cm x 2cm 3cm²
2 6cm x 4cm 12cm²
5 15cm x 10cm 75cm²
s 3s cm x 2s cm 3s² cm²
Now,
To see if the relationship between the scale factor and the area of scaled copies is proportional, we can calculate the ratio of the area to the scale factor for each row of the table:
Scale factor Corresponding dimensions Area Ratio of area to scale factor
1 3cm x 2cm 3cm² 3/1 = 3
2 6cm x 4cm 12cm² 12/2 = 6
5 15cm x 10cm 75cm² 75/5 = 15
s 3s cm x 2s cm 3s² cm² (3s²)/s = 3s
In each case, the ratio of the area to the scale factor is constant, which means that the relationship between the scale factor and the area of scaled copies is indeed proportional.
Therefore,
We can say that the relationship between the scale factor and the area of scaled copies is proportional.

Answer:
28m⁷n⁵
Step-by-step explanation:
You would first multiply 14 by 2. You would then multiply (which is really addition when it comes to exponents) your like-term exponents.
(14m²n⁵)(2m⁵) =28m⁷n⁵
14(2) = 28
m² + m⁵=m⁷
n⁵ + 0 = n⁵
Answer:
[tex]28 {m}^{7} {n}^{5} [/tex]
Step-by-step explanation:
14*2=28; m^2*m^5=m^7.
When you're working with multiplication of powers, you have to add the exponents. For example
[tex] {x}^{4} \times {x}^{2} = {x}^{6} [/tex]
Because
[tex] {x}^{4} = x \times x \times x \times x \\ {x}^{2} = x \times x \\ {x}^{4} \times {x}^{2} = x \times x \times x \times x \times x \times x = {x}^{6} [/tex]
