Answer:
QV = 36 UNITS
Step-by-step explanation:
Centroid of a triangle divides the median in the ratio 2 : 1.
QU is the median and V is Centroid. Therefore,
QV : VU = 2 : 1
Let QV = 2x & VU = x
QV + VU = QU
2x + x = 54
3x = 54
x = 54/3
x = 18
QV = 2x = 2*18 = 36
Answer:
Option C
Step-by-step explanation:
When you put the write the scenario in an equation, it'll look like
(5q+3)(5q-3) for the new width times the new length
Factor these, and you shall get 25q^2+15q-15q-9. Simplify that into
25q^2-9
The factor theorem says that for a function f(x), if f(a) = 0, then (x - a) is a factor of f(x).
For f(x) = 2x^4 + 22x^3 + 60x^2
f(-5) = 2(-5)^4 + 22(-5)^3 + 60(-5)^2 = 2(625) + 22(-125) + 60(25) = 1250 - 2750 + 1500 = 0
Therefore, x - (-5) = x + 5 is a factor of f(x).
