1) Temperature in Fahrenheit =77°F.

2) Temperature in Celsius= 25°C

3) Height of rectangular prism = 8 inches

4) Width of rectangle = 40 inches

Step-by-step explanation:

1) If Temperature is 25°C . How many degrees Fahrenheit is it?

The formula to calculate temperature in Fahrenheit is:

$F=(C\times\frac{9}{5})+32$

Putting value of Celsius:

$F=(C\times\frac{9}{5})+32 \\F=(25\times\frac{9}{5})+32\\F=(5\times9)+32\\F=45+32\\F=77$

So, 25°C in Fahrenheit is 77°F.

2) If temperature is 77°F,what is the temperature in Celsius?

The formula used is:

$C=(F-32)\times\frac{5}{9}$

Putting value of Fahrenheit is:

$C=(F-32)\times\frac{5}{9}\\C=(77-32)\times\frac{5}{9}\\C=45\times\frac{5}{9}\\C=25$

So, temperature in Celsius is 25°C.

3) The volume of triangular prism is 64 inches³. The length is 2 inches and width is 4 inches. What is height.

The formula of finding volume of triangular prism is:

$V=L\times W\times H$

Putting values:

$V=L\times W\times H\\64=2\times 4\times H\\64=8\times H\\H= 64/8\\H=8$

So, height of triangular prism is 8 inches.

4) The area of rectangle is 80 inches. if length is 20 inches what is the width of rectangle.

The formula used is:

$Area=Length\times Width$

Putting values:

$Area=Length\times Width\\80=20\times Width\\W=80/20\\W=40$

So, width of rectangle is 40 inches.

15 POINTS!! I NEED TO KNOW THE ANSWER WITHIN 2 HOURS!!! PLEASE HELP!!

<h3>Answer: x*a^2 or a^2*x</h3>

======================================

Work Shown:

a^(b+2) = a^b*a^2 ... break up the exponent

a^(b+2) = x*a^2 ... replace a^b with x

We don't know the value of 'a' nor the value of x, so we cannot evaluate further. This is the same as a^2*x because order of multiplication does not matter. For example, 2*3 = 6 and 3*2 = 6, so 2*3 = 3*2.
