The perimeter of a rectangle is 86cm.
Its shortest side has a length of 15cm.
State the length of the longest side
Answer:
The length of the longest side is 28cm
Step-by-step explanation:
Rectangles have two pairs of equal sides, this means that if one of the sides is 15cm, there will be another side with 15cm. So to solve the problem we should first add the length of both sides we have, which are 15cm and 15cm, and will equal 30cm. Then we subtract 30cm from the 86cm so we know what the length of the last two sides is equal to when added together, that will be 56cm. Remember, we know that these last two sides have equal lengths. This means all we have to do is divide 56cm by 2 which will equal 28cm. This means that the length of one of the longest sides is 28cm.
Hope this helped!
What is the inequality
Answer:
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
Step-by-step explanation:
the graph of y=x^2 +4x + 3 is shown
a) what are the coordinates of the turning point
b) what are the coordinates of the roots of the equation x^2+4x+3=0
Answer:
a) -2, -1
b) (-3,0) and (-1,0)
From the graph of the given equation
the coordinates of the turning point is [tex](-2,-1)[/tex]
The coordinates of the roots of the equation [tex]x^2+4x+3=0[/tex] are [tex](-3,0) \; and \;( -1,0)[/tex]
Given :
the graph of y=x^2 +4x + 3 is shown
The graph of [tex]y=x^2 +4x + 3[/tex] is attached below
From the graph we can see that , the vertex is (-2,-1)
The graph changes direction at the point (-2,-1)
so we can say that there is only one turning point at [tex](-2,-1)[/tex]
Now we find out the roots of the equation
roots are the points where the graph crosses or touches x axis
The graph crosses x axis at [tex]-3 \; and \; -1[/tex]
The coordinates of the roots of the equation [tex]x^2+4x+3=0[/tex] are [tex]-3 \; and \; -1[/tex]

Find the gcf of the following numbers using continuous division. Write ur answer
1.) 24 and 72
3.) 24,32 and 48
2.) 18,27 and 45
4.) 24 and 36
Pls answer I need it thank you!
Answer:
Step-by-step explanation:
The continuous division method is an effective method to determine the GCF of two or more numbers, aside from the listing method where we are listing down the common factors before determining the greatest among them.
In continuous division, we are just simply dividing the numbers by their common factors until such time that we find no more common factors except for 1 to them to be divided. After which, we will just multiply the common factors that we used to divide them. The result will be our GCF. Let us try the exercise given above:
1. Find the GCF of 24 and 72
2 / 24 72
2 / 12 36
2 / 6 18
3 / 3 9
/ 1 3
Since we keep on dividing the numbers by 2 for 3 repetitions, we arrived at 3 and 9 by which we divide by 3 and we get 1 and 3 which we can no longer divide. So the GCF is: 2x2x2x3 = 24
Therefore, the GCF of 24 and 72 is 24.
2. Find the GCF of 24, 32 and 48
2 / 24 32 48
2 / 12 16 24
2 / 6 8 12
/ 3 4 6
So the GCF is: 2x2x2 = 8
Therefore, the GCF of 24, 32 and 48 is 8.
3. Find the GCF of 18, 27 and 45.
3 / 18 27 45
3 / 6 9 15
/ 2 3 5
So the GCF is: 3x3 = 9
Therefore, the GCF of 18, 27 and 45 is 9.
4. Find the GCF of 24 and 36.
2 / 24 36
2 / 12 18
3 / 6 9
/ 2 3
So the GCF is 2x2x3 = 12
Therefore, the GCF of 24 and 36 is 12.

If you add the equations in system A we get 6x+7y=32, If we add the equations in system B we get 8x+8y=40. Explain why (3,2) is still a solution to both of these equations.
Step-by-step explanation:
(3,2) is the solution to both equations because if you substitute the the x and y values you get a true statement for example
6(3) + 7(2) =32
18 + 14 = 32
32=32
that is a true statement
you can do the same with system B
8(3) +8(2)=40
24 + 16 = 40
40 =40
which is a true statement
On a floor plan for Rosedale Middle School, 1 inch represents 10 feet. If Sarah's classroom is 2 inches by 3 inches on the floor plan, what are the actual dimensions of her classroom?
The actual dimensions of Sarah's classroom are 20 feet by 30 feet, based on a scale of 1 inch representing 10 feet on the floor plan.
If 1 inch on the floor plan represents 10 feet in reality, we can determine the actual dimensions of Sarah's classroom by multiplying the dimensions on the floor plan by 10.
The width of Sarah's classroom on the floor plan is 2 inches, so the actual width would be 2 inches * 10 feet/inch = 20 feet. Similarly, the length of Sarah's classroom on the floor plan is 3 inches, so the actual length would be 3 inches * 10 feet/inch = 30 feet.
Therefore, the actual dimensions of Sarah's classroom are 20 feet by 30 feet. This means that the classroom occupies a rectangular space with a width of 20 feet and a length of 30 feet. It is important to note that these measurements are scaled up from the floor plan according to the given ratio of 1 inch to 10 feet.

A rectangular carpet measures 12m by 5m. Part of the carpet is covered by a square rug of length 2m. What fraction of the carpet is covered by the rug?
Answer:
¹/15
Step-by-step explanation:
Area of the rug = s²
Where s = 2 m
Area of the rug = 2² = 4 m²
Area of the rectangular carpet = length × width
Where,
Length = 12 m
Width = 5 m
Area = 12 × 5 = 60 m²
Fraction of the carpet covered by the rug = area of the rug ÷ area of the carpet = 4/60 = ¹/15

The required nonreal solution of the given equation 4x⁴ – 8x³ + 4x² – 128x – 960 = 0 is –4i, 4i.
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
Here,
The given expression,
4x⁴ – 8x³ + 4x² – 128x – 960 = 0.
Factorization
4.(x + 3).( x - 5).(x² + 16) = 0
Now,
x + 3 = 0 ; x - 5 = 0 ; x² + 16 = 0
x = -3 ; x = 5 ; x = ± 4i
