Answer:
5(5k²+6)(4k-3)
Step-by-step explanation:
100k³ - 75k² + 120k - 90
Take 5 common above:
= 5(20k³ - 15k² + 24k - 18) ------- eq1
First let simplify 20k³ - 15k² + 24k - 18
= (20k³ - 15k²) + (24k - 18) ---------eq2
Factor out 6 from 24k - 18 :
6(4k-3)
Factor out 5k² from (20k³ - 15k²):
5k²(4k -3)
eq2 becomes: = 6(4k-3) + 5k²(4k -3)
Factor out common term 4k-3
(6+ 5k²)(4k -3) or (5k²+6)(4k-3)
Thus eq1 becomes:
5(5k²+6)(4k -3)
FORMULAS
Surface Area (Circle): Radius x Radius x 3.14 (Radius = Diameter / 2)
Surface Area (Rectangle/Square): Length x Width
Volume (Circle/Rectangle/Square): Surface Area x Average Depth x 7.5
Average Depth: (Shallow Depth + Deep Depth) ÷ 2
(Note: Constant Depth = Average Depth)

Answer:
x=0
Step-by-step explanation:
3=3(x-5)-3(x-6)
3=3x-15-3x+18
3+15-18=3x-3x
18-18=0x
0=0x
x=0
