Hello, we need to see it as a difference of two squares as we know that for all a and b real numbers

So, here

Voila !
Thank you
9 and 3. Because 9 is a composite number (3*3 = 9) and 3 is a composite number (1*3 = 3).
Answer:
Step-by-step explanation:
10x+10y=-10
9x+10y=18
= 10x+10y=-10
-9x-10y=18
= x=8
step two is to find y:
10x+10y=-10
10(8)+10y=-10
80+10y=-10
10y=-90
y=-9
your answer:
(x,y)= (8,-9)
Solution:
<u>We know that:</u>

<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>

<u>Cancel out the "2" by dividing it by 18.</u>

<u>Simplify the multiplication.</u>

Yes they are both equivalents because they are whole's and some examples would be 8/8,9/9,4/4. and 5/5 because they are all whole's 7 out of 7 pieces of pizza is the whole pizza.
