For this case we have the following expression:

The first thing we must do is to rewrite the expression as the product of two binomials.
To do this, we add similar terms.
We have then:

Then, doing distributive property we have:

Adding similar terms:
Answer:
The simplified expression is:
well there is 7x4, 14x2, and 28x1 of course.
Answer:
Therefore the game board is divided into 81 smaller squares.
Step-by-step explanation:
Given that, there is a square game.
Consider x be length of one side the square.
The volume of the square is = side ×side
=x² square units
Since the length of side of smaller square is one-ninth of the game board.
Then one side length of the smaller square is
units.
The area of a smaller square is 

Let a number of square is formed from the game board.
a ×The area of one smaller square= The area of game board.
According to the problem,



Therefore the game board is divided into 81 smaller squares.
10(the number of tests) divided by 5(the amount of weeks)=2. That is 2 tests every week. 2x7 weeks is 14 tests.
Or this could be a trick question and he could have only had tests for 5 weeks.
This is the same question as from DINW 220, but I will answer.
This form of the straight line is an equation through the two points and it reads => y-y1= (y2-y1)/(x2-x1) (x-x1), point 1 (-16,8) and poin2 (4, -2) , x1= -16, y1= 8, x2= 4 and y2= -2 =>
y-8 = (-2-8)/(4-(-16)) (x-(-16)) => y-8= -10/(4+16) (x+16) =>
y-8= (-10/20) (x+16) If we simplify fraction (-10/20) we get (-1/2) =>
y-8=(-1/2) (x+16) we will multiply the both sides of the equation with number (2) we get 2y-16= ( -1) (x+16) => 2y-16= -x -16, we will add to the both sides number (+16) => 2y= -x than divide the both sides with number (2) we get y= (-1/2)x where -1/2 is coefficient of direction or (slope) and this linear function have not cut on the y axis, because it goes through a coordinate start ( 0,0) in the decartes coordinate system.
