If 2 sq rt 2x = 2 sq rt 3, what is the value of x?
Arturiano [62]

Answer:

<u>The correct answer is x = 3/2</u>

Step-by-step explanation:

2 √2x = 2√3, what is the value of x?

Let's solve for x, this way:

2 √2x = 2√3

√2x = √3 (Dividing by 2 at both sides)

(√2x) ² = (√3) ²  (Raising both sides at the 2nd power)

2x = 3

x = 3/2 (Dividing by 2 at both sides)

<u>The correct answer is x = 3/2</u>

ankoles [38]

Answer:

196 meters,  it is not greater than Kayla's total.

Step-by-step explanation:

Given:

Kayla is using 492 meters of a string when she is done there is 49 meters  left.

Ella gives Kayla 3 times more than she has now.

To find:

How much did Ella give and is it greater than Kayla's total ?

Solution:

Kayla has now ( after using 492 meters of a string ) = 49 meters

Ella gives Kayla 3 times more than Kayla has now means,

49+3\times49 = 49 +147 = 196 \ meters

Therefore, Ella gave 196 meters string to Kayla.

Now, to find that is it greater than Kayla's total,

Kayla's total length of string = 492 + 49 = 541 meters

Kayla's total length of string is 541 meters while Ella gave 196 meters string to Kayla which is less than Kayla's total.

Thus, it is not greater than Kayla's total.
