Given A(-3, 6) and B(0, 6), what are the coordinates of point P that lies on segment AB, such that AP:PB = 2:1? A: (2, -2) B: (-
DerKrebs [107]

Answer:

(-1 1/2, 6)

Step-by-step explanation:

The mid point between A(-3,6) and B(0,6) represents the coordinates of point P, which is (x,y)

Hence,the coordinates, that is, AP: x = (-3 + 0)/2 = -3/2 = -1 1/2

also, BP: y = (6 + 6)/2 = 6

Therefore, the coordinates of point P = ( -1 1/2, 6)

Write the quadratic equation in standard form:<br> 7x + 8 + 2x2<br> 2x + 1 + x2
JulsSmile [24]

Answer:

3x^2 + 9x  +9

Step-by-step explanation:

Given

(7x + 8 + 2x^2) + (2x + 1 + x^2)

Required

The result in standard form

We have:

(7x + 8 + 2x^2) + (2x + 1 + x^2)

Remove brackets

7x + 8 + 2x^2 + 2x + 1 + x^2

Collect like terms

7x+ 2x  + 8 + 1 + 2x^2+ x^2

9x  + 9+ 3x^2

The standard form of a quadratic equation is:

ax^2 + bx + c

So, we have:

9x  + 9+ 3x^2

3x^2 + 9x  +9

What is the value of "x" if 25^2 = x
olga55 [171]
The value of x would be the answer of 25^2 which means it is squared and squaring means a number times itself, so, therefore you have 25x25 which would give you the answer of 625 meaning x=625
