Hello,
Step-by-step explanation:
2x² - 7x - 15 = (x - 5) (2x + 3)
x - 5 = 0 ⇔ x = 5
2x + 3 = 0 ⇔ x = -3/2
Answer:
Well a midpoint makes the cutter segment or Line in exactly in half. So the two lines cutted are equal. In this case t is the midpoint. PT and TQ are equal. So you have two expressions, make then equal to each other since they are congruent.
6x+4=8x-8
12=2x
x=6
Now PT is 6x+4
So we subsitute x for 6 since x=6
6*6+4
40
PT is 40
When it's x²/a² - y²/b²=1 it's the one with zeros on the x axis, at x=±a, y=0.
Here the zeros are at (±5,0) so that's the first page, second graph.

70p
C) 3y(2y+9)
Step-by-step explanation:
you have to divide 6 and 2 then you have to use a factor of 27 to get 9.
