Answer: (7 + d) 4 and 4 (7 + d)

Step-by-step explanation:

4 (d + 7) = 4d + 28

(7 + d) 4 = 28 + 4d (flipped version of 4d + 28)

4 (7 + d) = 28 + 4d (the same)

16 POINTS HELP ASAP plzzzzzzzzz

Answer:

$\large\boxed{\large\boxed{\sqrt{3}$

Explanation:

You are comparing irrational numbers.

By inspection, i.e. at first sight you can only compare $\sqrt{3} \text{ }and\text{ } 2\sqrt{3}$ because they have the same radicand.

You can order: $\sqrt{3}$

You can introduce the 2 inside the radical by squaring it:

$2\sqrt{3}=\sqrt{2^2\times3}=\sqrt{12}$

Since 5 is between 3 and 12, you can order:

$\sqrt{3}$

Which is:

$\sqrt{3}$

You must know that π ≈ 3.14.

5 is less than 9 and the square root of 9 is 3; hence, $\sqrt{5}$ and $\sqrt{5}$

Now you must determine whether π is less than or greater than $\sqrt{12}$

Using a calculator or probing numbers between 3 and 4 you get $\sqrt{12} \approx3.46$

Hence, the complete order is:

$\sqrt{3}$

Cost of a New Car From 1970 to 1990, the average cost of a new car, C

Lunna [17]

Answer:

In year 1986 the average cost of car is $12,000

Step-by-step explanation:

Cost function:

C = 30.5t² + 4192

Cost = $12,000

Find:

Year

Computation:

C = 30.5t² + 4192

12,000 = 30.5t² + 4192

t = 16 year

So,

Year 1970 + 16 year

1986

So, In year 1986 the average cost of car is $12,000
