-3•-4=12, and -3+-4=-7.
this will turn into
(x-3)(x-4)
set them up to equal zero
x-3=0, x-4=0
solve
x=3, x=4
(a)
20% of 50 is 10
Half of 50 is 25
25 + 10 = 35
50 -35 = 15
15 of the backpacks were neither pink or blue
Hope this helps :)
Answer:addition and multiplication
Step-by-step explanation:
I just did it
We can calculate it by PVOA table.
PVOA means present value of an ordinary annuity.
PMT = $350
PMT means recurring payment.
time = 5 years and interest rate is 4%
So n = 5 and i = 4%
So we can calculate PVOA as
PVOA = PMT times (PVOA factor for n = 5 and i = 4%)

(PVOA factor PVOA table)

So present value is $1558.2
