Answer:
The given expression
on multiplying is 
Step-by-step explanation:
Consider the given two expressions
and 
We have multiply both expressions,

To multiply two terms first multiply constant numbers that is 6 × 2 = 12
For x , y and z apply property of exponent,

Then power of x together will be,

Similarly for y powers,

Since first term do not have any expression for z so it will remain same.
Thus, the given expression on multiplying become,
is 
Steps:
1. Draw a long box
2. Draw a horizontal line down the center of the box
3. Draw three equal sections in the top half ; shade in 1 segment
4. Draw 6 equal sections in the bottom half; shade in 2
Answer:
Option 1.1
Step-by-step explanation:
The linearization of a curve implies the use of calculus to find the local value for the derivative and approximating the function by the use of the formula

The function is given in such way that it's much easier to find the derivative by implicit differentiation than isolating any of the variables

Differentiating with respect to x, we have
Computing y' in the given point (3,1) we have
4(3)(1)+2(9)y'+y'=2


The function will be approximated with the expression

To find the approximate value for x=2.8
The correct value is the option 1.1
You need do like 25$--------100% of real price
x$---------70%
25x70=100<u>x</u>
1,750=100<u>x</u>
<u> x</u>=1750<u />divided by 100=17.5$
