Answer:
{-1, 5} (two real solutions).
Step-by-step explanation:
On the left side we want x^2, not x?
We need to rewrite x? = 4x - 5 in standard form, that is, as a quadratic with x terms in decreasing powers of x:
x^2 - 4x + 5 = 0
This factors easily to (x - 5)(x + 1) = 0.
We let each factor equal zero (0) separately and solve for x:
{-1, 5} (two real solutions).
Answer:
300 feet
Step-by-step explanation:
If we were using feet the expression would be 198x, where x is feet per second
Since they are asking in meters we need to convert feet to meters
When you do that you get 60
Now the expression is 60x
When you plug 5 into the equation it is 300
Answer:
2%
Step-by-step explanation:
After 4 cards are drawn at random, that leaves 48 cards. 1 divided by 48 is .0208.
Hence, 2%
Answer:
21
Step-by-step explanation:
<em>Step 1: add 2 to 5</em>
=> 2 + 5
=> 7
<em>Step 2: Multiply the result by 3:</em>
=> 7 * 3
=> 21
Therefore the <u>final answer = 21</u>
