Step-by-step explanation:
Answer: 12
Step-by-step explanation:
I will assume those are coordinates.
The distance between 2 points is given by √ (x2 − x1)^2 + (y2 − y1)^2.
Replacing the values, we get √ (5 − 5)^2 + (6 − -6)^2 = √0+144 = 12
Answer:
(-1,-2)
Step-by-step explanation:
I graphed the equation on the graph below so you can see that (-1,-2) is a solution.
Answer:
100
Step-by-step explanation:
Answer:
135 units²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
To calculate h use Pythagoras' identity on the right triangle on the left
h² + 8² = 17²
h² + 64 = 289 ( subtract 64 from both sides )
h² = 225 ( take the square root of both sides )
h =
= 15 , thus
A = 9 × 15 = 135 units²
