Answer:
D
Step-by-step explanation:
It cannot be Option A because the values are halve and there is nothing to distribute to them to make the values equal.
It's not option C because if you distribute 2y to each term in the parenthesis
you get -4
+ 6y³ + 4y². But where is the 8y² and -2y?
While Option B is equivalent, you can factor it out more and find the common factor of -2 to distribute among them as shown in option D
It is option D because distributing the -2y to each term solves to
-4 + 6y³ + 8y² -2y.
Answer:
A 50% increase
Step-by-step explanation:
Area = length x breadth
Let illustrate this with an example
original dimensions
length = 4
breadth = 5
area = 4 x 5 = 20
new dimensions
length = 4/2 = 2
breadth = 5 x 3 = 15
area = 15 x 2 = 30
Percentage change = 30 - 20 / 20 x 100 = 50%
Answer:
The slope is -2/3
Step-by-step explanation:
To find the slope of a line between two points, we use the equation
m = (y2-y1)/ (x2-x1)
where (x1,y1) and (x2,y2) are the two points
m = (12-8)/(4-10)
= 4/-6
= -2/3
The slope is -2/3
Answer:
x=2
Step-by-step explanation:
10x+4=2x+20
10x-2x=20-4
8x=16
x=2
