Answer:
n = the first
n + 1 = the 2nd
n + 2 = the 3rd
n(n + 2) - (n + 1) = 10(n + 2) + 1
n2 + 2n - n - 1 = 10n + 20 + 1
n2 - 9n - 22 = 0
(n - 11)(n + 2) = 0
If two factors = 0, at least one must = 0.
n - 11 = 0
n = 11
11,12,13
n + 2 = 0
n = -2
-2,-1,0
Answer:
Same speed.
Step-by-step explanation:
divide Distance by speed
25.5/3=8.5mph
34/4=8.5mph
The two lines are perpendicular because both of the lines intersects
Answer:
Step-by-step explanation:
hello :
note :
Use the point-slope formula.
y - y_1 = m(x - x_1) when : x_1= -4 y_1= -14
m= 3 (parallel means same slope)
an equation in the point-slope form is : y +14 =3(x+4)
Answer:
The measurement of side LI = 24
Step-by-step explanation:
In the question, it is given that Quadrilateral IJKL is reduced to quadrilateral I'J'K'L' which is 1/2 the times of measurement of side of the Quadrilateral IJKL
I'L' = 12
And IL will be 2 times the measurement of I'L'
Hence, IL = 2*12 = 24
