the answer is 4.5 ft

Step-by-step explanation:

Step-by-step explanation:

Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,

18/x = 8/2

Let's solve for x as required.

We have,

18/x = 8/2

=>Cross multiply:

18 × 2 = 8 × x

36 = 8x

=>Divide both sides by 8

36/8 = x

4.5 = x

x = 4.5 ft

Answer:

  153 square units

Step-by-step explanation:

The figure is drawn in the attachment with some lengths and points labeled.

The figure can be considered to have an area that is the sum of the areas of rectangle ABFE and triangle FGH, with the area of triangle BCD subtracted.

That area is ...

  A = area(ABFE) +area(FGH) -area(BCD)

  = (15)(9) +(1/2)(9)(6) -(1/2)(6)(3)

  = 135 +27 -9 = 153 . . . square units

Explain the difference between lateral and surface area below. If you are given the total surface area, then how could you deter
SVETLANKA909090 [29]

Lateral surface area is given as the area of all sides of a figure excluding the area of the base where as surface area is the sum of the areas of all faces of the solid.

Step-by-step explanation:

Lateral surface area is given as the area of all sides of a figure excluding the area of the base where as surface area is the sum of the areas of all faces of the solid.

If given total surface area, you can find lateral surface area by subtracting the area of the base from the surface area of the solid.

This is a challenging problem ? can someone help
Dafna11 [192]
The opposite sides of a rectangle are equal, so we can write the following equations:
2x = 3y + 5 ...........(1)
x = 2y + 2 .............(2)
Multiply equation (2) by 2, to get:
2x = 4y + 4 ...........(3)
The right hand sides of equations (1) and (3) are equal, so we can write:
3y + 5 = 4y + 4
which gives y = 1 as the solution.
Plugging y = 1 into equation (2), we find the x = 4.
So the full solution is: x = 4, y = 1.

Please I need help with that question
fomenos

We know that 2x + 5 = 10 - 3x, and because of this we can solve for x.

2x + 5 = 10 - 3x

+3x

5x + 5 = 10

-5

5x = 5

/5

x = 1

We can plug x into each x value to verify if this is true.

2(1) + 5 = 10 - 3(1)

2 + 5 = 10 - 3

7 = 7
