I believe it is -81k^2
-27k^3-81k^2-81k-27
If you would like to solve 7x - (25x^2 + 12x), you can do this using the following steps:
7x - (25x^2 + 12x<span>) = 7x - 25x^2 - 12x = - 25x^2 - 5x
</span>
The correct result would be <span>- 25x^2 - 5x.</span>
Answer:
x=3, y=5
Step-by-step explanation:
To find x:
Because opposite sides of a parallelogram are congruent, we can set up the equation 2x+5=12x-25. Solving the equation will show that x=3.
To find y:
Using the same method as x, we can find that y=5.
Hope this helped!
13 is 40 but idk what 14 is. Pls mark brainliest
Ok
relation of diameter to radius
2 radius=1diameter
radius=1/2 diameter
2r=d
d/2=r
circumfernce=2pir
since 2r=d
circumference=2d
so
c=pid=2pir
so if ou have circunference and you want to find diameter and radius
c=pid
divde both sides by pi
c/pi=d
c=2pir
divide both sides by 2pi
c/(2pi)=r
so
r=c/(2pi)
d=c/pi
