The first x is x=-7, and the second x=1
IgorLugansk [536]3 years ago

X² + 6x + 9 = 16
x² + 6x + 9 -16 = 16 -16
x² + 6x + 9 -16 = 0
x² + 6x -7 = 0

and then find the factor:
(x + 7) (x  - 1) = 0
x + 7 = 0    ;    x - 1 = 0
x = -7         ;    x = 1
and there is your factors

Which is an equation in point-slope form for the line that passes through the points (−1,4) and (3,−4) ? y+4=2(x−3) y+4=−2(x−3)
beks73 [17]

Answer:

y-4=-2(x+1)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(-4-4)/(3-(-1))

m=-8/(3+1)

m=-8/4

m=-2

y-4=-2(x-(-1))

y-4=-2(x+1)

The coordinate points of T are (0,6). The midpoint of ST is (6,-8). Find the coordinate of point S.
givi [52]

Answer:

The coordinates of the point S =  (12, -22)

Step-by-step explanation:

The coordinate points of T = (0,6)

Mid point of ST = (6,-8)

Let the coordinates of S = (a,b)

Now, BY MID POINT FORMULA:

If (x, y) and (z, w) are the line point joining line segment and (p,q) is the coordinate of mid point. Then

(p, q)  = (\frac{x  + z}{2}  , \frac{y + w}{2} )

So, here similarly, (6, -8)  = (\frac{(0+a)}{2}  , \frac{6+ b}{2} )

⇒ 6   = \frac{0+a}{2}  , -8 =  \frac{6+ b}{2}

⇒ a =2 x 6 = 12, b = 2 (-8) -6 = -22

⇒(a,b) = (12, -22)

Hence, the coordinates of the point S =  (12, -22)

Two sides of a right triangle measure 2 units and 4 units.
wel

Answer:

20

Step-by-step explanation:

using pythagorean theorem to find the hypotenuse gives √20, so the measure of the side of the square is also √20, square that to give the area of square, which is 20
