Answer:
x = -6 x=4
Step-by-step explanation:
x^ 2 + 2 x = 24
Subtract 24 from each side
x ^2 + 2 x-24 = 24-24
x^2 +2x -24 = 0
Factor
What 2 numbers multiply to -24 and add to 2
6*-4 = -24
6+-4 = -2
(x+6) (x-4) =0
Using the zero product property
x+6 =0 x -4=0
x+6-6=0-6 x-4+4=0+4
x = -6 x=4
1 foot, 8 inches is the correct answer
Yes the absolute value of 2 is 2!
$38*75% (the amount of the original price you pay) is $<span>28.50
$</span>28.50*1.06 (the cost of the book (100%) and the cost of the tax on top (6%)) is $<span>30.21
The customer pays a total of $</span><span>30.21 for the book</span>
Step-by-step explanation:
A(3,6)
x1,y1
B(11,12)
x2,y2
midpoint of AB(X,Y)
X= <u>x1</u><u> </u><u>+</u><u>x2</u>
2
= 3+11/2
= 7.
Y= <u>y1</u><u>+</u><u>y2</u>
2
= 6+12/2
= 9
AB(7,9)
