Is 5x +4 equivalent to 5(x-1) +9

Can anyone help me with this question please thank you!

Answer:

B. The individual events are dependent. The probability of the combined event is 3.772%.

Step-by-step explanation:

The individual events are dependent because you would have to draw 2 red candies in a row. After the first drawing, there would be one less red candy in the bag, which would affect the second drawing.

First drawing probability: 11/54, or 20.370%

Second drawing probability: 10/54, or 18.519%

Combined probability: 20.370*18.519 = 3.772%

The area of this rectangle is 54 square inches. Create an equation to find the value of n. Length is 3(n-1) and the width is n+2

olasank [31]

Value of n is 4

The area of a rectangle is equal to the product of its length and width.

we know ,

the area of rectangle, multiply the length, , and the width, ,

and set the product equal to the area.

area of rectangle = length * width

54 = 3(n - 1) * (n + 2)

54 =( 3n - 3) * (n + 2)

multiply ( 3n - 3) with (n + 2)

we get,

54 = $3n^{2} + 6n - 3n -6$

54 = $3n^{2} + 3n -6$

54 = 3( $n^{2} + n -2$ )

$\frac{54}{3}$ = ( $n^{2} + n -2$ )

18 = ( $n^{2} + n - 2$ )

$n^{2} + n - 2$ - 18 = 0

$n^{2} + n - 20$ = 0

solve them

$n^{2} + 5n + 4n -20$ = 0

n (n + 5) - 4 (n + 5) = 0

(n + 5)(n -4)

then we get,

n = -5 , n = 4

value of n should not be negative . so value of n is 4

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.

The area of a rectangle depends on its sides. Basically, the formula for area is equal to the product of length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides. Hence, we can say, the region enclosed by the perimeter of the rectangle is its area

Area of rectangle = Length x Breadth

A = lb

how to Factoring Quadratic Equation

Step 1: Consider the quadratic equation ax2 + b x + c = 0

Step 2: Now, find two numbers such that their product is equal to ac and sum equals to b.

(number 1)(number 2) = ac

(number 1) + (number 2) = b

Step 3: Substitute these two numbers in the formula given below:

(1/a) [a x + (number 1)] [a x + (number 2)] = 0

Step 4: Finally simplify the above equation.

QUESTION 10, 11, 12 and 13, 40 POINTS FOR CORRECT AWNSER AND WILL BE BRAINLIEST PLS BE FAST!! I WILL DO ANYTHING U WANT

10. The missing conversion is 20.32 inches

11. Total number of red cars is 34

12. Total number of blue cars is 36

13. Total number of silver cars is 70

<h3>What is Ratio?</h3>

Ratio is the number of times a quantity is contained more or less than another in a whole.

Analysis:

10. If 1 inch = 2.54cm

Then 8 inches = 8 x 2.54cm = 20.32 cm

First car park: Total number of cars = 60

ratio of red:blue:silver = 1:2:3

Total ratio = 1+2+3 = 6

number of red cars = 1/6 x 60 = 10

number of blue cars = 2/6 x 60 = 20 cars

number of silver cars = 3/6 x 60 = 30

second car park: Total number of cars = 80

ratio of blue: red: silver = 2:3:5

total ratio = 2+3+5 = 10

number of red cars = 3/10 x 80 = 24

number of blue cars = 2/10 x 80 = 16

number of silver cars = 5/10 x 80 = 40

11. Total number of red cars = 10+24 = 34

12. Total number of blue cars = 20+16 = 36

13. Total number of silver cars = 30+40 = 70
