Step-by-step explanation:
1) -9 = 9 true/false
the answer is false because negative and positive quite unlike in terms.
2) -(-21) = -21
Using the symbols multiplication rule,
Where,
<h2>
+ × + = +</h2><h2>
- × - = +</h2><h2>
- × + = -</h2><h2>
+ × - = -</h2>
Therefore, -(-21) = +21 = 21
⟼ 21 = -21 
<span>4x(x) + 3(2x) and 4x2 + 6x => 4x^2 + 6x and 4x^2 + 6x
5(3x) - 4(3x) and 3x => 15x-12x=3x and 3x
4(3a) - 2(4a) and 4a2 => 12a-8a=4a and 4a^2
3(3a) + a(3a) and 3a2 + 9a => 9a+3a^2 and 9a + 3a^2
Can you spot the one which is different?
</span>
<span>reflection in the x -axis, counterclockwise rotation by 90° ,the translation P(x,y)→P′(x+2,y+3)</span>
It is already in it's simplest form, however, if you are trying to distribute it then the answer would be 1x/3x.
Hope this helps!
Answer:
Assuming it is a square with side length 3.2 then the area is:
10.24 units squared
Step-by-step explanation:
Assuming the figure s a square with sides 3.2 by 3.2 then the area is found by multiplying the sides.
3.2 * 3.2 = 10.24 units squared
