Use ax^2 + bx + c = 0
ac = -8
b = 2
The factors are 4 and -2.
Plug them into the equation:
x^2 + 4x - 2x - 8
Then factorise it:
x ( x + 4) - 2 (x + 4)
so m = 4
(x + 4)^2
Answer:
(1,1)
Step-by-step explanation:
M=(x1+x2 / 2 , y1+y2 / 2)
M=(-2+4 / 2 , 4+ -2 / 2)
M=(2 / 2 , 2 / 2)
M=(1,1)
Using the Pythagorean theorm,
a^2 + b^2 = C^2, where a nd b are the side lengths and c is the hypotenuse ( diagonal line)
If it was a square both sides would be the same length so we would have:
13^2 +13^2 = c^2
169 + 169 = c^2
338 = c^2
c = SQRT(338) = 18.38
18.38 is larger than the 15.26 given in the problem , so the room is not a square.
