Simplify √36x²y3 and you get
↓↓↓
√18 x y ³
Fisrst one is just add the functions
(f+g)(x)=f(x)+g(x)=
8x^2+16x+6+x^3-3x^2-9=
(f+g)(x)=x^3+5x^2+16x-3
multiply
ok
f(x)g(x)=(x^3-4x+2)(x^2+2)
just multiply and expand yourself because I don't have my graphing calculator with me right now
we know that
A quick way to estimate the sum of two numbers is to round each number and then add the rounded numbers
case a) We round the number to the nearest hundred
so
Round up is equal to 
Round up is equal to 
Find the estimate sum
case b) We round the number to the nearest tens
so
Round up is equal to
Round down is equal to 
Find the estimate sum
If you combine 2z and -z you get z.
Answer:
a) $1.40 b) $9.35 c) $57.50
Step-by-step explanation:
a) The tax on the burger will be 3% of the cost of the burger.
This means 0.03 of 46.75 (0.03 x 46.75) = $1.40 tax
b) 20% of pre tax bill as tip would be:
0.20 of 46.75 (0.20 x 46.75) = $9.35 tip
c)Total cost of dinner including tax and tip would be:
Original Cost + Tax + Tip
= 46.75 + 1.40 + 9.35
= $57.50 total
