To find the volume of all 4 pans, you will use the formula for finding the volume of a rectangular prism and then multiply it by 4 because they are all the same size.

7 in. x 7 in. x 2 in. - 98 cubic inches

98 cubic inches x 4 = 392 cubic inches.

The expression that puts this all together is:

4 (7 x 7 x 2) or 4(98).

In a rectangle ABCD if AB=4x and DC=7x-9,find the length of AB.(Lengths are in cm).
myrzilka [38]

Answer:

12 cm

Step-by-step explanation:

AB and DC are parallel to each other, so they are the same length. Set their lengths equal to each other and solve for x

4x = 7x - 9

4x - 7x = 7x - 7x -9

-3x = -9

-3x/-3 = -9/-3

x = 3

Now solve for AB.

AB = 4x

AB = 4(3)

AB = 12

Use the picture below to find the length of x. Round your answer to the nearest hundredth.
valentinak56 [21]

Answer: 6.71

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

Work Shown:

The longest horizontal portion of length 6 breaks up into two equal pieces of length 3 each. Focus on the smaller right triangle on the right hand side. This right triangle has legs of 3 and 6. The hypotenuse is x.

Use the pythagorean theorem with a = 3, b = 6, c = x to find the value of x

a^2 + b^2 = c^2

3^2 + 6^2 = x^2

9 + 36 = x^2

45 = x^2

x^2 = 45

x = sqrt(45)

x = 6.7082039

x = 6.71

Supplementary angle must add up to 180 so the supplement will be 108 degrees. 180-72=108.
