Answer:
StartRoot 2 squared + 6 squared EndRoot
Step-by-step explanation:
we have
A(4,3) and B(-2,1)
we know that
the formula to calculate the distance between two points is equal to

substitute the given values



therefore
StartRoot 2 squared + 6 squared EndRoot
Answer:
21 cm by 21 cm
Step-by-step explanation:
The formula for the area of a square is A = x^2, where x is the length of any one side of the square. Here,
441 cm² = x²
This actually has two roots: {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.
The dimensions of the square are 21 cm by 21 cm.
Answer:
-4
Step-by-step explanation:
Answer:
h(1) = -2
Step-by-step explanation:
What h(1) is saying is the value of x = 1. We need to find the y-value.
We see from the graph that when x = 1, y = -2.
