Answer:
-24
Step-by-step explanation:
-1(3^2)+(-15)
-9+(-15)
-24
It is 1200 feet. This is a variation of a 5-12-13 triangle. I could use Pythagoras to show what's up
1300^2 = 500^2 + b^2
1690000 = 250000 + b^2
b^2 = 1690000 - 250000
b^2 = 1440000
b = 1200 feet
Answer:
x = 12
Step-by-step explanation:
7x=8x-12
take away the 7x from both sides
0=x-12
add 12 to each side
12=x
check it
7(12)=8(12)-12
84=96-12
84=84
