Answer:
$392. No they don't have enough money to pay for the trip.
They need $255 more dollars, which would take 14 weeks and 2 days.
Step-by-step explanation:
18 x 4 = 72
320 + 72 = 392
647 - 392 = 255
255/18 = 14.2
With in quadrant 3, we should expect both and to be negative, so that is positive. The corresponding reciprocal expressions will have the same sign.
Recall that , which means
Also recall that , so
Only the first two options are correct.
5(x + y)
Here we are given the expression:
Now let us equate it to zero to find x first,
Now subtracting 18 from the other side,
taking square root on both sides,
So we will get two values of x as ,
Now we can write square root -1 as i,
So our factors become,
The final factored form becomes,
