The answer is 2.5, but if you say it isn't then maybe it can be as a fraction 
or 
.
Using the distributive property, we have -12w^2-2w since a(b+c)=ab+ac
Hope this helped
Answer:
<em>3. No.</em>
<em>4. No, not necessarily.</em>
<em>5. Yes.</em>
Step-by-step explanation:
3. No. With the two triangles, she knows that one angle of each is a right angle. She does not know anything about side lengths. She cannot prove the triangles are congruent.
4. We cannot prove the triangles are congruent. With the perpendicular segments, there is a pair of congruent, right angles. Then there are two pairs of sides that are congruent, but the order is SSA, and SSA does not prove triangles congruent.
5. Using the two sets of perpendicular lines, you have two congruent, right angles. Then you have the other pair of given congruent angles. Finally, segment RT is congruent to itself. This makes AAS. the triangles are congruent.
The solution is A
x=2 y=-1
the solution is where the two lines intersect
