The length of a rectangle is 4 less than twice the width. If the perimeter of the rectangle is 130, find the length of the rectangle.

Answer:

A

Step-by-step explanation:

-4(x^2+14x+49)-6

-4x^2-56x-196-6

-4x^2-56x-202

Answer:

F(x)=-4x^2 - 56x - 202

Answer:

Step-by-step explanation:

Given equation of a straight line is,

y = -4 - 2x

Domain of the line (x) → {-3, -2, -1, 0, 1}

Therefore, range for the given set of domain will be,

Range (y) → {2, 0, -2, -4, -6}

[By substituting the value of x in the given equation we get the value of y]

Set of scatter points are,

(-3, 2), (-2, 0), (-1, -2), (0, -4), (1, -6)

Now we plot these points to get the discrete graph as attached.

Answer:

b) 54

Step-by-step explanation:

Area = [tex]\frac{ab}{2}[/tex] = [tex]\frac{9.12}{2}[/tex]

9 x 12 = 108

108/2 = 54

=> 54

hope this helps and is right :)

Answer:

161 ft squared

Step-by-step explanation:

8 x 5 x 2 = 80

8 x 7 = 56

5 x 5 = 25

80 + 56 + 25

56 + 25 =81

80 + 81 = 161

9 score is the answer ok plz give me brilliant

Answer:

4/3

Step-by-step explanation:

Moving from (-4, -9) to (5, 3), x (the 'run') increases by 9 from -4 to 5, and y (the 'rise') increases by 12 from -9 to +3.  Thus, the slope of the line connecting the two points is

m = rise / run = 12/9 = 4/3

It may help to think of the change in x (9) as the horizontal leg of a right triangle and the change in y (12) as the vertical leg.  Then  

m = (vertical leg length) / (horizontal leg length) = 12/9 = 4/3

Answer:

504

Step-by-step explanation:

In order to solve, you have to isolate n.

first combine like terms on the right side.

48×42=2016

4n=2016

Now to isolate the n, divide each side by four.

n/4=2016/4

n=504

Question number 13 is 18

Answer:

56 and 36 are the numbers.

Step-by-step explanation:

Let the numbers be x and y,

x + y = 92

x - y = 20

On solving,

y = 36

x = 56

can you add a picture of the problem?

Answer: D the final mean is higher than the original

Step-by-step explanation:

90+85+98+60+84+78/6= 82.5 as the original mean

dropping 60 which is the lowest grade means 90+85+98+84+78/5=87 which means the new mean is 87 which is greater than the original mean of 82.5

So the answer is D

Answer The small triangles each have an area of 12m^2 and the big rectangle had an area of 80m^2. This would mean that the combined area is 104m^2

Step-by-step explanation: The rectangle shape can be found by multiplying 8 by 10 to get 80m^2. The two triangles can be found by multiplying 4 (half of 8) by 6 and then dividing it by two. This would mean that the small triangles each have an area of 12.

The first option is the correct one, that is the valid probability distribution.

For any probability distribution we have two main rules.

So, with the second rule we can see which one of the tables is a valid distribution, we will see that for table A the sum is:

Sum(A)=  1

And for the other two:

Sum(B) = 1.08

Sum(C) = 0.9

So we can see that the only valid probability distribution is the one in the first option.

Answer:

Acute and Equilateral

Step-by-step explanation:

The little dashes on the sides indicate congruent sides

Each side has a singular dash meaning that all the sides are congruent. If all the sides are congruent then all of the angles are congruent

The angles in an equilateral triangle are 60

An acute triangle angles are all less than 90

All of the angles in a equilateral triangle are less than 90 therefore this is an equilateral acute triangle
