Answer:
B. 36+12sqrt(2)
Step-by-step explanation:
We can use Pitagoras' theorem to find the height of the triangle
15^2=9^2 + h^2
h^2=144
Lets apply square root to the whole equation:
sqrt(h^2=144)
h=12
With the height, we can now find the length of AC.
Sin(45)=12/AC.
AC=12/Sin(45)=24/sqrt(2)=12*sqrt(2) if we rationalize.
Now, lets fin the missing segment between B and C (call it)
where 9+x= BC
Cos(45)=x/AC
x=cos(45)*AC=12
Now, the perimeter is the sum of all its sides
AB+AC+BC=15+12*sqrt(2)+9+12=36+12sqrt(2)

They want to reach there goal so it’s more or equal to
Answer: -7 and 7
Step-by-step explanation:
-7*7= -49
and -7+7=0
To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second one. That means, keep the first fraction the way it is. Change the division to a multiplication. Flip the second fraction.
-8/3 / -2/6 = -8/3 * -6/2 = (8 * 6)/(3 * 2) = 8
Answer:
it will take him 35 minutws. because if he spends 5 minutes on each section and theres 7 sections it will take 35 minutes
