Answer:
- -5, -18
- -5x -18x
- (x -3)(6x -5)
Step-by-step explanation:
a) The factors of 90 are ...
90 = (-1)(-90) = (-2)(-45) = (-3)(-30) = (-5)(-18) = (-6)(-15) = (-9)(-10)
The sums of these factors are -91, -47, -33, -23, -21, -19.
The factor pair with the sum of -23 is of interest here. Those factors are ...
-5, -18
__
b) -23x = -5x -18x
__
c) The rewritten expression is ...
6x^2 -5x -18x +15
(6x^2 -5x) -(18x -15) . . . . group into pairs
x(6x -5) -3(6x -5) . . . . . . .factor each pair
(x -3)(6x -5) . . . . . . . . . . factor out the common factor (6x -5)
2/3x=10
x=10÷2/3
x=10×3/2
x=5×3
x=15
Answer:
the volume of the cone would be approximately 490.09 m^3.
Step-by-step explanation:
The volume of a cone is pir^2h/3
So it would be pi*6^2*13/3
=pi*36*13/3
=pi*156
=490.09
Therefore, the volume of the cone would be approximately 490.09 m^3.
I hope this helped and have a good rest of your day!
Your awnser is 120 if I’m wrong please tell me and I’ll help you again
Your gonna divide 72 by 2 so therefore you get 36
So that equals to Nicole’s age
