What is the value of x?

Mathematics

Hi there!

To find x, we'll need to proceed methodically. First, we'll start by finding the length of ST. The 30-60-90 relationship tells us that ST = 2. Then, we can find RT, also using the 30-60-90 relationship. RT = 4. Lastly, we can use the 45-45-90 relationship to determine that x = 4.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

If you save $3,000 at an interest rate of
juin [17]
Amount earned in compound interest = P(1 + r)^n; where P is the principal, r is the rate and n is the number of periods.

Amount = 3,000(1 + 14%)^6 = 3,000(1 + 0.14)^6 = 3,000(1.14)^6 = $6,584.91

Which expression has the greatest value when x=3
Luden [163]

Answer:

The third expression: (2x)^3

Step-by-step explanation:

Plug in 3 for x in each expression

2x^3

2(3)^3

Use PEMDAS

2 (3 × 3 × 3)

2 (9 × 3)

2 (27)

54

2x^3 + 5

(The last expression told us 2x^3 = 54 so feel free to use this information to make life easier)

54 + 5

59

(2x)^3

(2 × 3)^3

Use PEMDAS

6^3

6 × 6 × 6

36 × 6

216

(x - 1)^3

(3 - 1)^3

Use PEMDAS

2^3

2 × 2 × 2

4 × 2

8

216 is the greatest value so the third expression is the answer
