Answer:
x = 2, x = -6
Step-by-step explanation:
Subtract 8 from both sides.
Simplify.
Solve with quadratic formula.
a = 1
b = 4
c = -12
I do not have time to show work for quadratic formula parts.
I am so sorry for this inconvenience.
Answer: 3 3/7 hours
Step-by-step explanation:
you need to find out how much work they can do in an hour.
let x represent the total collaborative work
1/8 + 1/6 = 1/x
3/24 + 4/24 = 1/x
7x = 24
x = 24/7 or 3 3/7 hours (in decimal form this is 3.4286)
I cannot guarantee this is correct but hope it helped
2x+3x+4b
5x+4b
Hope this helps :)
Answer:
The total cost is $59.85
(rounded up from 59.846 since this problem is about money)
Answer:
To find a
sin 30=a/6in
1/2=a/6in
2a=6in
a=6in/2
a=3in
To find b
cos 30=b/6in
/3/2=b/6in
2b=/3*6in
b=2/3(two radical three)
I don't get the radical sign so I use / sign on the last 3 steps on the second
