It is an acute scalene triangle.
Answer:
C
Step-by-step explanation:
The expression at the top is equal to 12/10 or 6/5
Option C, or 4/5 x 3/2, is also equal to 12/10
Answer:
It would have taken 12day for 6person to build 12 computers
Step-by-step explanation:
Since
4person = 18days
1person = 4 x 18 = 72days
Therefore if two more person helped
4person + 2 person = 6person
6person = 72/6 = 12days
It would have taken 12day for 6person to build 12 computers
H=-3x^2-6x+5 subtract 5 from both sides
h-5=-3x^2-6x divide both sides by -3
(5-h)/3=x^2+2x halve the linear coefficient, square it, add it to both sides....
(2/2)^2=1 add 1 to both sides...
(5-h+3)/3=x^2+2x+1, now the right side is a perfect square...
(8-h)/3=(x+1)^2 multiply both sides by 3
8-h=3(x+1)^2 divide both sides by -1
h-8=-3(x+1)^2 add 8 to both sides
h=-3(x+1)^2+8
h(x)= -3(x+1)^2+8
