The equation used is 50 = (2w + 5) × w which can be used to find its width, w.

According to the question we are Given,

Length of rectangle = 5 inches more than its width

Area of rectangle = 50sq. inches

Let width of rectangle = w

So, According to the question,

length = 2w + 5

Area of rectangle = Length × Breadth

50 = (2w + 5) × w

So, our required equation is 50 = (2w + 5) × w

It was discovered that the pressure in atmospheres (atm), when applied to a balloon, was inversely related to the height in meters, squared root. The pressure was 1.44 atm when the balloon was 25 meters height in the air. What was the pressure like at a 9-meter height?

The pressure is 2.4 atm when the height is 9m.

Inversely proportion means when one variable is directly proportional to the reciprocal of the other, there is an inverse fluctuation between the two variables. In other words, the two variables' product has a fixed value. Therefore, as one variable rises, the other falls.

Here, We take pressure of atmosphere as P and the height of the balloon as H.

Given that, The pressure of atmosphere was inversely proportional to the square root of the height.

We write this as [tex]P[/tex]∝[tex]\frac{1}{\sqrt{H} }[/tex].

Taking constant of the proportionality as k.

[tex]P[/tex]=[tex]\frac{k}{\sqrt{H} }[/tex].

We have, The pressure was 1.44 atm when the balloon was 25 meters height in the air.

P=1.44 and H=25

[tex]1.44=\frac{k}{\sqrt{25} }[/tex].

[tex]1.44=\frac{k}{5}[/tex]

[tex]k=5\times1.44[/tex]

[tex]k=7.2[/tex]

Now [tex]P=\frac{7.2}{H}[/tex]

We have to find If H is 9m then what is P?

[tex]P=\frac{7.2}{\sqrt{9} }[/tex]

[tex]P=\frac{7.2}{3}[/tex]

[tex]P=2.4\\[/tex]

To meet her goal of riding a total of 28.8 miles, Keilantra needs to ride an average of 6.2 miles.

Here we know that Keilantra wants to rude her bicycle for a total of 28.8 miles.

We know that she has already ridden 4 miles, so the distance left to meet her goal is:

D = 28.8mi - 4mi = 24.8mi

Now we know that she wants to meet her goal in 4 days, so the average that she needs to ride in each of these 4 days is given by the quotient:

24.8mi/4 = 6.2 mi

To meet her goal, Keilantra needs to ride an average of 6.2 miles.

Power is the result of multiplying same number for n number of times.  The value of the given expression when simplified is equal to 75.

Power is the result of multiplying same number for n number of times. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

The given expression can be simplified as shown below.

(5⁴ × 3³) / (5² × 3²)

Answer: A

Step-by-step explanation:

Angles on a straight line must add up to 180 so angle BCA is 180-132=48

Because the triangle BAC is an isosoles angle BCA and ABC must be the same so 48

We can now use the angle on a straight line rule to figure out angle DBA 180-48=132

We know that triangle DBA is an isosoles trianlge so and x and DAB must be the same and both be x, and we know that angles in a triangle add up to 180 so the equation can be written as:

180=2x+132

48=2x

Step-by-step explanation:

We are given the points (2, -3), and (6,4), and we want to find the slope through these 2 points.

Even though we have 2 points (as stated in given), let's label their values to help avoid any confusion and mistakes.

[tex]x_1=2\\y_1=-3\\x_2=6\\y_2=4[/tex]

We can substitute the values of [tex]x_1, y_1, x_2,[/tex] and [tex]y_2[/tex] into the formula to find the slope. Remember that the formula has subtraction.

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

x(2x+5) = 3 and 2x²+5x = 3 are equivalent algebraic expression.

Equivalent expressions are those expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s). They are same but looks different.

Given that, x(2x+5) = 3 and 2x²+5x = 3 and we have to conclude how both expressions are related to each other.

Let's procced to solve this.

x(2x+5) = 3 ..............(1)

2x²+5x = 3 ...............(2)

Now, solving equation (1), we get

x(2x+5) = 3 ⇒2x²+5x = 3, which is equation (2)

So, when we solve equation (1), we get equation (2) and vice-versa.
