One is going 52 and the other 64
2 (x)+2 (x+12)=232 and solve
Answer:
The third side is sqrt(77)
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
2^2 + b^2 = 9^2
4+ b^2 = 81
Subtract 4 from each side
b^2 = 81-4
b^2=77
Take the square root of each side
sqrt(b^2) = sqrt(77)
b = sqrt(77)
The third side is sqrt(77)
30×·15=4.50
then subtract 30 by 4.50 to get 25.50
.0825×30=2.475
now add 2.475+25.50+30= 57.975 round to 57.98
15 + 20 equals to 35, 60 - 35 equals to 25 so so his total journey is 1 hour
x^2 − 8x + 9
What two numbers when multiplied yield 9 but when added yield -8?
There are no such numbers.
Use the quadratic formula.
