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)
Answer:
Step-by-step explanation:
The given expression is x-
= 2
and we have to solve this for the value of x,
( x-
) = (2)

x² - 15 = 2x
x² - 2x - 15 = 0
x² - 5x + 3x - 15 = 0
x ( x-5 ) + 3(x - 5) = 0
( x+3 )( x-5 ) = 0
( x+3) = 0
x = -3
or ( x- 5 ) = 0
x = 5
Therefore, x = -3 and 5 will be the solution.
Option E is the answer.
75 + 10 = 85
85 - 10 = 75
85 - 75 = 10
There is nothing to solve for.
Opposite reciprocal of each other
So two perpendicular liens would maybe have the slopes:
3 and -1/3
A 250 1 times 250 substract by 9000 gives 8750 them find loss of water by 9000 substracted by 8750
b 6250 11 times 250 substract by 9000 gives 6250.
c 9000 t=0 since no water it's being pumped out so answer is 9000
d 36 hours times 250 is 9000
