We can complete the square to get a standard form quadratic into vertex form. First, add Y and 34 to the right side of the equation. You’ll get -5x^2 + 30x = y + 34.
Next, you need to factor out a -5 from the left side, so you’ll get -5(x^2 -6x) = y + 34. Then, complete the square on the left. You’ll get -5(x-3)^2 = y - 11. Finally, add 11. The answer is y = -5(x-3)^2 + 11
If you multiply 48cm times 15cm,you get 720cm.Which would leave you with 60 left because 780 minus 720 equals 60.The height of the other base is 60cm.
Girl if you don’t look up the answers besides asking us
Answer:
I don't know exactly what you need but I have two ways.
Step-by-step explanation:
if you need to make an example: 6x55+ 6(3f-12)= or something along those lines.
or if you just need that answer then 330
I'm sorry if that's not what you were wondering
