Answer:
x = - 12, x = 2
Step-by-step explanation:
Given
x² + 10x = 24
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(5)x + 25 = 24 + 25
(x + 5)² = 49 ( take the square root of both sides )
x + 5 = ± = ± 7 ( subtract 5 from both sides )

$138494.7
Step-by-step explanation:
170828-73828=97000
97000÷12=8083.3
8083.3= the amount the house depreciated every year
8083.3×4 =32333.3
170828-32333.3= $138494.7
Answer:
0 = 10x^2 + 3x + 2
Step-by-step explanation:
That is the quadratic formula:
x = -b +- sqrt( b^2 - 4ac) / 2a
It is used for an equation in the form 0 = ax^2 + bx + c
so just plug a, b, and c, from the quadratic formula into that equation
First let’s write down what 2 fourth would look like. It would look like 2/4 (on the computer/phone it looks a little different, if you were to write it out the 2 would be over the 4). Now think is there anything that 2 and 4 can both be divided by. The answer is yes! They can both be divided by 2. So divide them both by 2. 2 divided by 2 is 1, and 4 divided by 2 is 2. So your answer becomes 1/2, or one half. There is nothing else they can both be divided by so that’s your final answer.
