Answer:
Two solutions are found:
n=0 , n= 4 ....
Step-by-step explanation:
n^2-4n = 0
Take common from the given expression:
n(n-4)=0
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately;
n(n-4)=0
n = 0.
n-4 = 0.
Add 4 at both sides:
n-4+4 = 0+4
n = 4
Therefore two solutions are found:
n=0 , n= 4 ....
Answer:
LCM of 24, 36 = 72
Step-by-step explanation:
24 = 24, 48, 72, 96
36 = 36, 72, 109
Answer:
Step-by-step explanation:
Because midpoints were used to make similar triangles we can say
AC=2(DE)
5x+12=2(9x-20)
5x+12=18x-40
-13x+12=-40
-13x=-52
x=4
AC=5x+12
AC=5(4)+12
AC=20+12
AC=32
