Sum means add
(x+5) + (-4x-2) + (2x-1)
=-3x+3+(2x-1)
=-x+2
Answer:
90 degrees.
Step-by-step explanation:
Considering a 40 degree angle is opposite to a 40 unit side, a 90 degree angle will be opposite to a 90 degree side.
A) 8m
B) p= 19m
P= s+s+s
P= 8+8+9
3/(x+2) = 2/x
multiply both fractions by x(x+2) to cancel out the bottoms
so it becomes 3x = 2x+4
ow subtract 2X from both sides and you get
x = 4
so it took Juan 4 hours
it took Yumi 2 hours more so 4+2 = 6 hours
So he has to pay $150 a month for 1 year.
so $150×12months = $1800
