Answer:

x = 12
y = 20

Step-by-step explanation:

There is nothing in this diagram to suggest any particular values for x and y.

If we assume the figure is intended to be a kite, symmetrical about its horizontal diagonal, then each segment is congruent to the one above it.

x = 12

y = 20

Find the surface area of the prism.

weqwewe [10]

Answer:

160 m²

Step-by-step explanation:

The surface area of the prism is the sum of the area of its surfaces. This prism has 5 surfaces, namely the front, back, right, left and bottom surface.

Area of front surface

Area of triangle= ½ ×base ×height

Base= 6 m

Height= 4 m

Area= 6(4)= 24 m²

Area of back surface

Area of back surface

= area of front surface

= 24 m²

Area of right surface

Area of rectangle= length ×breadth

Length= 7 m

Breadth= 5 m

Area= 7(5)= 35 m²

Area of left surface

Area of left surface

= area of right surface

= 35 m²

Area of bottom surface (base of prism)

Area of rectangle= length ×breadth

Length= 7 m

Breadth= 6 m

Area= 6(7)= 42 m²

The total surface area can be found by adding all of the surface areas we have found earlier.

Total surface area

= 24 +24 +35 +35 +42

= 160 m²

Find the x- and y-intercepts of 3x + 6y = 18

djyliett [7]

In order to find the x and y intercepts of an equation, you can plug in 0 for the opposite variable. Let us solve for the intercepts now.

x-intercept

We are going to plug in 0 for y and the solve for x:

$3x+6y=18$
$3x+6(0)=18$
$3x=18$
$x=6$

So now we know the x-intercept of the line is: (6, 0)

y-intercept

We are going to plug in 0 for x and solve for y:

$3x+6y=18$
$3(0)+6y=18$
$6y=18$
$y=3$

So now we know that the y-intercept for the line is: (0, 3)
