Well, it is 3 polynomials so let’s break it down first.
(-3x*2 -2xy +y*2) (-4x*2 -xy + 6y*2)
Let’s add these first. The rule is to drop parentheses and add regularly. Bases stay the same, powers add and coefficients multiply.
Ans: (-7x*4 -3x*2 y*2 + 7y*4)
Now let’s add it with the last one.
The answer is: -6x*6 +3x*3 y*3 -6y*6
Answer:
by SAS only
Step-by-step explanation:
based on the diagram we only have one side and one angle explicitly identified as equivalent.
but we have an implicit confirmation of the second side QS to the enclosed angle, because the triangles are presented that this side is the same for both triangles.
so, SAS applies (but no other, as we don't have any information on the 3rd side).
The mistake is the sign,
The sign must be switched
So therefore x > -5
Answer: 2.5%
Step-by-step explanation:
Let's use the rule of 3 here.
If the total price is $275,000 or 100% of the sale, then $6,875 is X% of the total sale.
Let's put money on one side and percentages on the other.

Solve for x;


Answer:
Function
Step-by-step explanation:
The following is a <em><u>one-on-one function</u></em> since neither the domain nor the range is being repeated.
