Answer:
C.x2 + 12x + 4x + 48
Step-by-step explanation:
Answer:
x² -25
Step-by-step explanation:
(x +5)(x -5) = x(x -5) +5(x -5) = x² -5x +5x -25 . . . . . 5x terms cancel
= x² -25
_____
This is an example of the factoring of the difference of squares:
(a+b)(a-b) = a²-b²
Answer:
The answer is B.
Step-by-step explanation:
The original graph of y = x^2 has a vertex at (0,0)
The formula for graph translations is y = (x-#)^2+#
The number inside the parentheses is a horizontal translation.
So, we are given y = (x-(-3))^2+#
The vertex of the graph moves 3 points left, since the number is negative (-3).
The number at the end of the equation is a vertical translation.
So, we are given y = (x+3)^2+4
The vertex of the graph moves 4 points up, since the number is positive (4).
The new vertex is at (-3,4)
Answer:
distance = 6 units
Step-by-step explanation:
using the Pythagorean theorem:
distance² = 10² - 8² = 100 - 64 = 36
distance = √36 = 6 units
