Answer:

$\large\boxed{A=45\ cm^2}$

Step-by-step explanation:

It's a parallelogram.

The formula of an area of a parallelogram:

$A=bh$

b - base

h - height

We have b = 9cm and h = 5cm. Substitute:

$A=(9)(5)=45\ cm^2$

Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. How

KIM [24]

$20 is the base cost (y intercept)
$0.50 is the cost per ride (slope)
Plug into an equation
Y = 20 + 0.50x
35 = 20 + 0.50x
15 = 0.5x, x = 30

Solution: 30 rides

Find one value of x that is a solution to the

maksim [4K]

Answer: x = {+-sqrt(3), +-2*sqrt(3)}.

Step-by-step explanation:

(x^2 - 8)^2 + (x^2 - 8) = 20

▪︎ Let (x^2 - 8) be y.

Then,

y^2 + y = 20

y^2 + y - 20 = 0

D = b^2 - 4ac = 1 + 20*4 = 81 = 9^2

y1 = (-b - sqrt(D))/(2a) = (-1 - 9)/2 = -10/2 = -5

y2 = (-b + sqrt(D))/(2a) = (-1 + 9)/2 = 8/2 = 4

1) x^2 - 8 = -5

x^2 = 8 - 5

x^2 = 3

x = +-sqrt(3)

2) x^2 - 8 = 4

x^2 = 8 + 4

x^2 = 12

x = +-sqrt(12)

x = +-2*sqrt(3)

A rectangular picture frame has a width of 9 cm and a length of x cm.

VladimirAG [237]

We are asked to find for an expression that represents the perimeter of a picture frame which has a shape of a rectangle. The dimensions given are length of size x cm and a width of size 9 cm.

The formula for the Perimeter of a rectangle is given by
P=2L+2W

where L is the length and W is the width of the rectangle.

Hence,
P=2(x)+2(9)
Simplifying this values would give us a result of,
P=2x+18

Therefore, 2x+18 is the expression that represent the perimeter of the picture frame.

a. The next 5 palindromes for the car's odometer are <u>28982, 29092, 29192, 29292, and 29392 miles</u>.

b. After setting the trip's odometer to 0 to determine the number of miles the trip is, the next 5 palindromes for the trip are <u>11, 22, 33, 44, and 55 miles</u>.

c. The next time that both the car's odometer and the trip's odometer will be a palindrome is when the car's odometer reads <u>39993</u>, while the trip's odometer reads <u>11111</u>.

<h3>What is a palindrome?</h3>

A palindrome is a word, phrase, or sentence that remains the same when spelled or written backward or forward.

As a Greek word, palindrome combines 'again' (Palin) and 'to run' (Drom).

Thus, once a word or number reads the same backwards as it is forwards, it is a palindrome.
