Answer:
<h3>
vertex = (h, k) = (5, -9)</h3>
Step-by-step explanation:
The answer is 3
This is because to find the volume of X, you just do the side length of X^3, and to find the volume of Y, you do Y^3.
Since both of these values are to the power 3 (X^3 and Y^3), you need to undo it to find the side length of X divided by the side length of Y, and to undo this you need to do something called cube rooting
And the cuberoot of 27=3
Answer:
Step-by-step explanation:
x²+10x+21=0
x²+10x+(10/2)²-(10/2)²+21=0
x²+10x+25-25+21=0
(x+5)²-4=0
(x+5)²=4
(x+y)²=(x+y)(x+y)=x(x+y)+y(x+y)=x²+xy+xy+y²=x²+2xy+y²
(x+y)²=x²+2xy+y²
coefficient of x=2y
y²=[(coefficient of x)/2]²=(2y/2)²=y²
