If a rectangle has the sides 5x-3 and 6x-4 what is the area and perimeter

Answers

Step-by-step explanation:

[tex]A = lw[/tex]

[tex]A=(5x-3)(6x-4)[/tex]

[tex]A=30x^2-20x-18x+12[/tex]

[tex]A=30^2-28x+12[/tex]

[tex]P=2(l + w)[/tex]

[tex]P = 2(5x - 3 + 6x - 4)\\P=2(x-7)\\P=2x-14[/tex]

Answer:

[tex]Perimeter = 22x - 14[/tex]

[tex]Area = 30 {x}^{2} - 38x + 12[/tex]

Step-by-step explanation:

Length of rectangle (l) = 5x - 3

Weidth of rectangle (w) = 6x - 4

Perimeter of the rectangle = [tex]2(l + w)[/tex]

[tex] = > 2(5x - 3 + 6x - 4)[/tex]

[tex] = > 2(11x - 7)[/tex]

[tex] = > 22x - 14[/tex]

Area of the rectangle = [tex]l \times w[/tex]

[tex] = > (5x - 3)(6x - 4)[/tex]

[tex] = > 5x(6x - 4) - 3(6x -4)[/tex]

[tex] = > 30 {x}^{2} - 20x - 18x + 12[/tex]

[tex] = > 30 {x}^{2} - 38x + 12[/tex]

Find the median: In a particular year, approximately 1.7 million people took the mathematics section of a college achievement test. Of these, 44% scored less than 490, 45% scored less than 500, 48% scored less than 510, 51% scored less than 520, and 57% scored less than 530. In what interval is the median score? The median score is in the interval â–¼(Choose one).

Answers

Answer:

the median score would be between 510 and 520

Step-by-step explanation:

The computation of the median score is shown below

In the case of the continuous probability distribution, the median value is the mid value in which the number is equal to fall to above or below it

Here

P(X = median) = 0.5 = 50%

So the median score would be between 510 and 520

Hence, the same is to be considered

Step-by-step explanation:

Triangle DCE is similar to EGF

CE/EF=DE/EG

Substitute

(8x-1)/21=(6x+3)/17

Cross multiply

(8x−1)*(17)=(6x+3)*(21)

136x−17=126x+63

Subtract 126x from both sides

10x−17=63

Add 17 to both sides.

10x−17+17=63+17

10x=80

Divide both sides by 10.

x=8

Earl runs 50 meters in 20 seconds. How many meters does Earl run per second?

Answers

Answer:

2.5 meters

Step-by-step explanation:

Answer:

Earl can run 2.5 meters in one second.

Step-by-step explanation:

We know that Earl can run 50 meters in 20 seconds. That means he can run 150 meters in one minute and 9,000 meters (or 9 kilometers) in one hour. 50 meters / 20 seconds = ? meters / 1 second

50 meters / 20 seconds = x / 1 second

(50 x 1) = (20) (x)

50 = 20x divide both sides by 20 to get the "x" alone

50 / 20 = x

2.5 = x

Step-by-step explanation:

Between 1 whole, there are four lines in it. Thus:

4 lines --- 1 whole

1 line --- [tex]\frac{1}{4}[/tex]

P is at the 3rd line from zero, so its value is [tex]\frac{1}{4}[/tex] × 3 = [tex]\frac{3}{4}[/tex]

Thus, the opposite of P would be -[tex]\frac{3}{4}[/tex].

Which functions are even? Check all of the boxes that apply.
f(x) = x2 – 3x + 2
7x) = -2)
f(x) = |x|

Answers

Answer:

C) f(x) = |x|

Step-by-step explanation:

Determine if Odd, Even, or Neither

         f (x) = |x|

Find f (−x) by substituting −x for all occurrence of x in f (x). f(−x) = |−x|

Make −x positive.

        f(−x) = |x|

A function is even if  f(−x) = f(x).

Check if  f(−x) = f(x).

        |x| = |x|

Since |x| = |x|, the function is even.
