Answer: C
Step-by-step explanation:
the equation for X is
use proportion to solve
2 + x = 16
x = 14
(14,y)
The equation for Y is
use proportion to solve
-1 + y = 6
y = 7
(14,7)
now use the distance formula
(14,7) (2,-1)
which gets you 14.4 or C
So hmmm x²+6x+8=0
alrite.. let's do some grouping now
( x² + 6x + [?]²) + 8 = 0
notice above, we have a missing fellow in order to get a perfect square trinomial... hmm who would that be?
let's take a peek at the middle guy of the trinomial.. 6x.. hmmm let's factor it, 2*3*x, wait a minute! 2 * 3 * x... we already have x² on the left-side, since the middle term is just 2 * the square root of the other two terms, that means that the guy on the right, our missing guy must be "3"
alrite, let's add 3² then, however, bear in mind that, all we're doing is borrowing from our very good friend Mr Zero, 0
so if we add 3², we also have to subtract 3², let's do so
(x² + 6x +3² - 3²) + 8 = 0
(x² + 6x +3²) + 8 - 3² = 0
(x+3)²=3² - 8
(x+3)² = 1
Answer: first of all, i would put it in an equation. then i would slove that and use that answer.
Step-by-step explanation:
use the equation <u>12X x 15 = y </u>
<u>12x=15</u>
12 12
x= 180
You put 6 on one side then equal it to 9 with at variable of "X" with it multiplied by 3 to make the thing an equation
Answer:
One length = 10
Two length = 20
One width = 2
Two width = 4
Step-by-step explanation:
The perimeter is 24
A rectangle has 4 sides
2 are length
other 2 is width
First, the length is 8 inches longer
there are 2 length so 8 + 8 = 16
That leave 8 inches left
divide 8 by 4 = 2
Add one length together
8 + 2 = 10
2 is the width
How to check you answer:
10 + 10 + 2 + 2 =24
