Answer: 4x-20=58

                   +20 +20

               4x=78

                /4  /4

                 x=19.5

Step-by-step explanation: Parenthesis first. Multiply 4 times x (which is 4x) and 5 times 4 (which is 20). So you get 4x-20-2=56. Move the (-2) over to the other side using inverse operations, making it 4x-20=58. Then move over the 20, again using inverse operations, making it 4x=78. Then isolate the variable by dividing both sides by 4 leaving you with x=19.5. You can check the work by plugging it in:

4(19.5-20)-2=56

78 - 20 = 58  (moved the -2 over to the other side)

58 = 58. That is true so the answer is correct.

Answer:

52√3 ft ²

Step-by-step explanation:

Formula for area of the trapezoid:

A=\frac{a+b}2h

a = Base = 11

b = Base = 15

h = Height = 4√3

Since the height is  4√3 we can turn it into a number:

4√3 = 6.92820323028 = 6.93

Now using the formula:

A=\frac{a+b}2h=\frac{11+15}2\times6.93=90.06664 =90.07

As you can see that it not a answer choice.

We can turn the answer choice into number:

44√3 ft ² = 76.21023553.. ≈ 76.20

44√3-24 ft ²=52.21023553.. ≈ 52.20

60√3 ft ² = 103.92304845.. ≈ 103.90

52√3 ft ² = 90.06664199.. ≈ 90.07

Thus, the answer is 52√3 ft ²

If it moves 4.5 times a year and each time it moves 10 meters, one one year it moves 45 meters. Now we want 11 years, so that's 45 times 11 which would give you 495 meters in 11 years
