(5x+1)+(5x+2)=28
(because ab+bc=ac)
10x+3=28
10x=25
x=2.5
then plug 2.5 into ab equation:
5(2.5)+1=ab
ab=13.5
Answer:
B. $63.19
Step-by-step explanation:
You will pay $63.19 for a item with original price of $78.99 when discounted 20%. In this example, if you buy an item at $78.99 with 20% discount, you will pay 78.99 - 15.798 = 63.19 dollars.
Hello,
1) Conditions:
x+2>=0==>x>-2
x>=0
So x>=0
1/5 ln(x+2)^5 +1/2 [ln x -ln(x^2+3x+2)^2]
=ln(x+2)+ ln√x - ln(x+1)(x+2)
