Area=base*height
A=(x+6)(2x+2)
A=2(x+1)(x+6) technically this is the simplified form, but they may want the expanded form...
A=2x^2+14x+12
Perhaps the most concise way to factor is by "completing the square" which is how the quadratic formula is derived...
x^2+6x+8=0 move constant to other side, subtract 8 from both sides
x^2+6x=-8, halve the linear coefficient, square it, then add that to both sides, in this case (6/2)^2=3^2=9
x^2+6x+9=1 now the left side is a perfect square of the form
(x+3)^2=1 take the square root of both sides
x+3=±√1 subtract 3 from both sides
x=-3±√1
x=-3±1
x=-4 and -2
Since the zeros occur when x=-4 and -2 the factors of the equation are:
(x+2)(x+4)
1. copying
3. arc
4. ridgid motion
5. Distance Formula
6. image
7. transformation
8. translation
I don't really know if these are correct because I have never had to define any of those words or know a lot of these. But some of them I am pretty sure are right. I hope I helped some. I am sorry if I didn't. But this is my best guess.
Answer:
Step-by-step explanation:
the answer is
$194 (start) / <u>100 (100%)</u> = $1.94 (1%)
$1.94 * 7 = $13.58 (7%)
$13.58 * <u>13 (13 years)</u> <em>= $176.54 </em>
$194 (start) + <u>$176.54 (interest)</u> <em>= $370.54</em>
