Answer: D. 21ways.
Step-by-step explanation:
This is based on selection, fixing two '3' numbers into 5numbers to make it 7 numbers can be done in 7C2 ways.
Generally, nCr = n!/(n-r)!r!
7C2 = 7!/(7-2)!2!
=7!/5!2!
=7×6×5!/5!×2!
=7×6/2
=21ways (D)
Answer:
-14
Step-by-step explanation:
the coordinate of I :
H = 8+I /2
-3 = 8+I /2
8+I = 2×(-3)
8+ I = -6
I = -6-8
I = -14
Answer:
x = -21/11
Step-by-step explanation:
6(2x + 4)2 = (2x + 4) + 2
12(2x +4) = 2x + 4 + 2
24x + 48 = 2x +6
22x = -42
x = -21/11
d) 10, -3
Hope I helped! ( Smiles )
The answer would be 1/8 because when 1/8 is divide into the endpoints of AB you will recieve 1/8 of the endpoint numbers. Like 1/8 of 4 would be written as 1/8 times 4/1 since its a fraction multiply 1 times 4 and 8 times 1 to get 4/8. 4 goes into 4 one time and into 8 2 times giving you 1/2. Hope this helped.
