Answer:

For 2 the answer is 12. For 3 the answer is 28.

Step-by-step explanation:

These may be wrong but hopefully they are correct

My work:

$5^2+11^2=146$ then $\sqrt{146} = 12.08$

$\sqrt{421}=20.5$ $19^2+20.5^2=781.25$ then $\sqrt{781.25} =28$

Answer:

2. 12.08

3. 7.74

Step-by-step explanation:

a squared + b squared = c squared

2. 5 squared = 25, 11 squared = 121, 25 + 121 = 146, the squre root of 146 is 12.08

3.19 squared = 361, 421 - 361 = 60 60 squared = 7.74

EASY QUESTIONS ON THE EARTH

Question #10:

To find what fraction of an onion is used per serving, divide the total amount of onion by the total number servings.

1/2 ÷ 6 = 1/12

Therefore, 1/12 of an onion was used per serving.

Question #12:

1/2 of 3/4 means that we multiply 1/2 to 3/4.

3/4 * 1/2 → 3/8

3/4 of 1/2 means we multiply 3/4 to 1/2.

1/2 * 3/4 → 3/8

Therefore, both expressions are similar.

Best of Luck!

What is the answers to the question: Which rational expression is undefined when x = 0?

Rom4ik [11]

Answer:

option D

$\frac{4x-8}{-2x^2}$

Step-by-step explanation:

An expression is undefined when you get division by zero or in simple words when denominator is zero.

Now we will solve each expression one be one by plugging value of x = 0

$\frac{5(0)-4)}{3(0)-3}$

-4/-3 = 4/3

$\frac{6(0)}{9(0)-3}$

0/-3 = 0

$\frac{8x+6}{-x^2+1}$

$\frac{8(0)+6}{-0+1}$

6/1

$\frac{4x-8}{-2x^2}$

$\frac{4(0)-8}{-2(0)}$
