Answer:
The answer is 
Step-by-step explanation:
We have to:

So, if we take the 60 degree angle of the smallest triangle, we have to:

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

Then:



Answer:
Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
Matthew bought his cat, Filmore, at Mr. Macintosh’s pet store in Lincoln, Nebraska. (could do “!” at the end too)
1.) 2a - 4b + 3ab -5a + 2b
= 3ab -3a -2b
2.) 4(2x+1)-3x
= 8x+4 -3x
= 5x + 4
3.) 4(p-5) +3(p+1)
= 4p-20 + 3p+3
= 7p -17
4.) 6(p+3q) - (7 + 4q)
= 6p+18q -7 -4q
= 6p + 14q -7
5.) 4rs -2s -3(rs +1) -2s
= 4rs -4s -3rs -3
= rs -4s - 3
