If x=12 in, y=16, and z=20 in, what is the surface area of the geometric shape formed by this net?
maria [59]

Given:

x = 12 in, y = 16 in and z = 20 in

To find:

The surface area of the geometric shape.

Solution:

Area of top rectangle = z × z

                                    = 20 × 20

Area of top rectangle = 400 in²

Area of middle rectangle = z × y

                                          = 20 × 16

Area of middle rectangle = 320 in²

Area of bottom rectangle = z × x

                                          = 20 × 12

Area of bottom rectangle = 240 in²

Area of left triangle = \frac{1}{2}yx

                                $=\frac{1}{2}\times16\times12

Area of left triangle = 96 in²

Area of right triangle = \frac{1}{2}yx

                                $=\frac{1}{2}\times16\times12

Area of right triangle = 96 in²

Surface area = 400 + 320 + 240 + 96 + 96

                     = 1152

The surface area of the geometric shape is 1152 in².

What is the slope of the line represented by the equation 6y-14x=5
ioda

Answer:

slope = \frac{7}{3}

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 6y - 14x = 5 into this form

add 14x to both sides

6y = 14x + 5 ( divide all terms by 6 )

y = \frac{14}{6} x + \frac{5}{6} ← in slope- intercept form

with slope m = \frac{7}{3} ← in simplest form

Bojangles has a rectangle-shaped roof with a width of 6x^2 feet and a length 12x^3. What is the area of the roof?
emmainna [20.7K]

area of rectangle = length x width

this is the formula to find it.

now , put the values of length and width,

=> area= 12 x 3 x 6 x 2

=> area =  432 feet^2

Hope this helps!
