You mean 2x3x12? if yes, it is 72.
Answer:
ernie=X so Daniel = X-6
Step-by-step explanation:
Answer:
y-intercept (0,11/5)
x-intercept (11/2,0)
Step-by-step explanation:
The y-intercept is obtained when the x-coordinate equals 0 (x=0)
so the y-intercept is (0,11/5)
The x-intercept is obtained when the y-coordinate equals 0 (y=0)
In this case
0 = -(2/5)x+11/5---->(2/5)x = 11/5 ----> x=(5*11)/(5*2) = 11/2
So the x-intercept is (11/2,0)
Answer:
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
using the identity
cos2a = 2cos²a - 1 , then
cos2a
= 2[ 
(a + 
) ]² - 1
= 2 [ 
(a² + 
+ 2) ] - 1
= (a² + ) + 1 - 1
= (a² + ) ← thus verified
