Replace all variables in the given equation with the given values.
Answer: 37
Let n represent the number.
.. (n -9)^2 = n -3 . . . . . the square of 9 less than the number is 3 less than the number
.. n^2 -18n +81 = n -3
.. n^2 -19n +84 = 0
.. (n -7)(n -12) = 0
.. n = 7 or 12
The number could be 7 or 12.

Check:
.. (7 -9)^2 = (-2)^2 = 4 = 7 -3 . . . . answer checks OK
.. (12 -9)^2 = 3^2 = 9 = 12 -3 . . . . answer checks OK
Answer:
m=-6
Step-by-step explanation:
use slope formula to solve
m= rise/run=y2-y1/x2-x1
The answer is x+2 and x-1
Answer:
LSA = 592cm^2.
Step-by-step explanation:
Well LSA is the SA but without the base so the blue square does not count.
So we have to find the area of the triangle which is b*h/2.
So 18.5*16 / 2 is 148.
And since there is 4 triangles with the same dimensions we do 148*4, 592cm^2.
