The number is -13.
In order to find this, we first need to make each part of the statement into a mathematical statement.
Twice the difference of a number and 2.
2(x - 2)
Three times the sum of the number and 3
3(x + 3)
Now we can set them equal to each other and solve.
2(x - 2) = 3(x + 3) ----> Distribute
2x - 4 = 3x + 9 ------> Subtract 2x from both sides
-4 = x + 9 -----> Subtract 9 from both sides
-13 = x
parallel when a=2
perpendicular when a=-1/2
Answer:
4^9+8 or 4^17
Step-by-step explanation:
X² = hyp² - cat²
x² = 625 - 156.25
x² = 468.75
x ≈ 21,6
