Answer:

True. By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal, so the result is irrational.

Answer:

True

Step-by-step explanation:

Example: sqrt(5) (which decimals continue forever) will mean that if you did 5+sqrt(5) it would still have those decimals.

My favorite recipe for lemonade calls for 4 cups of water to 3/4 cups sugar. How
Nikolay [14]

Answer and Step-by-step explanation:

To find the unit rate, divide the 4 cups of water and the \frac{3}{4} cups sugar by 4 to get a unite rate for 1 cut of water.

<u>4 divided by 4 equals 1.</u>

<u />

<u />\frac{3}{4}<u> divided by 4 equals </u>\frac{3}{16}<u>.</u>

<u />

<u>Now, we multiply </u>\frac{3}{16}<u> by 6.</u>

<u></u>\frac{9}{8}<u> is how many cups of sugar that needs to be measured for 6 cups of water.</u>

Find the positive solution and please explain how ;4;
valentina_108 [34]
(x + 2)² - 10 = 0 (assuming it's equal to zero)

Expand the binomial: (x + y)² = x² + 2xy + y²
Thus, x² + 4x + 4 - 10 = 0
x² + 4x - 6 = 0

x = \frac{-4 +_- \sqrt{16 + 24}}{2} (by quadratic formula)
= \frac{-4 +_- \sqrt{40}}{2}
= \frac{-4 +_- 2\sqrt{10}}{2}
= -2 + \sqrt{10}, since we're taking the positive solution.
