Answer:
1600
Step-by-step explanation:
As you can see, this is a difference of squares. We can plug it into our differences of squares formula to get the answer:
(a+b)(a-b)
(58+42)(58-42)
(100)(16)
= 1600
Hope you learned something!
When finding the slope between two points, we simply take (y2-y1) / (x2-x1)
For this, we can substitute the following to get this :
y2-y1 and x2-x1
1 - 4 and 7 - 1
-3 and 6
-3 / 6 gets you -1/2
Therefore the answer is :
The slope of the line is -1/2
Sum means add
(x+5) + (-4x-2) + (2x-1)
=-3x+3+(2x-1)
=-x+2
The correct answer is A. D
That is because D has a horizontal line of symmetry, as can be seen on it.
