Use the square root method to find the solutions to the quadratic equation 22

lakkis [162]

Answer:

$x = 2\sqrt{2}, -2\sqrt{2}$

Step-by-step explanation:

Given

$x^2 - 8 = 0$

Required

Solve

We have:

$x^2 - 8 = 0$

Add 8 to both sides

$x^2 = 8$

Take square roots of both sides

$x = \±\sqrt{8}$

Expand

$x = \±\sqrt{4*2}$

This gives:

$x = \±2\sqrt{2}$

Split

$x = 2\sqrt{2}, -2\sqrt{2}$

Three apples and twice as many oranges add up to one half the number of cherries in a fruit basket. how many cherries are there?

posledela

So, there are 3 Apples. Oranges = 2 * 3 Apples = 6 Oranges.
The sum of the number of Oranges and Apples represent half of the Cherries.
Mathematically speaking, o + a = 1/2 c <=> 3 + 6 = 1/2c. => c=18.
So there are 18 Cherries.

Todd says that he can make 10 if he adds 32 coins to 28 coins. Is he correct? Explain how you know using words.

Andreas93 [3]

He was wrong, you cannot make 10 coins by adding 32 coins to 28 coins. If you want to obtain 10 coins from 32 coins and 28 coins, you can subtract 28 coins from 32 coins.
This can be illustrated as follows:
32-28=10
