The solutions are: x = 6; x = -4.
Explanation: The given equation is:
x^2 -2x -24 = 0
x^2 -6x + 4x - 24 = 0
x(x-6) + 4(x-6) = 0
(x-6)(x+4) = 0
=> x = 6
=> x = -4
Hence the solutions are: x = 6; x = -4.
Answer:
The answer have negative sign.
Step-by-step explanation:
<em>Subtract by 6 both sides of equation.</em>
<em>Simplify.</em>
<em>Divide by -4 both sides of equation.</em>
<em>Simplify to find the answer.</em>
<em>
, is the correct answer</em>
Answer:
A
Step-by-step explanation:
First, multiple 3 by 44 to find the number of pencils total. 3x44=132.
Then, divide 22 into 132. 132/22=6.
Therefore, each student received 6 pencils.
The best way to multiply complicated problems mentally* is to break them into chunks.
Start with 20 times 8 to get 160, and then 8 times 5 to get 40. Add these together to get 200. 200 times 3 is 600, and 20 times 200 is 4000. Add these together to get your final answer, 4600.
In other words 8 x 20 + 8 x 5 = 200 200 x 3 + 200 x 20 = 4600
*I assumed you meant mentally, because otherwise you'd just multiply longhand, multiplying two of the three numbers and then multiplying their product with the third.
