Greetings from Brasil...
Here we have an indeterminacy 0/0
We can change variable or rationalize.......
Let's rationalize
{[√(X + 4) - 2]/X} · {[√(X + 4) + 2]/[√(X + 4) + 2]} = 1/[√(X + 4) + 2]
So, the limit will be 1/4
ANSWER: $66.30
WORK:
to find 15% off, multiply by 0.15.
78 x 0.15 = 11.7
note: this is the percent off, so it's subtracted to find the sale price.
78 - 11.70 = 66.3
So
Total cost of the workbooks is d
And the number of workbooks is t
Therefore d = 95
95=19t
t=95/19=5
5 workbooks
5y-10 and 2y-6 unless the two are together in which case are they being added or multiplied (the equations).
Let's name the number 'n'. Now write an equation. 7*n +n^2 =12Now you can form a quadratic. n^2 +7n-12=0. Now you can use a myriad of methods to solve it. If you still need help, just message me.
