8z=4(2z+1)
First you would distribute the constant into the numbers in the parentheses. so
8z=8z+4
then you would combine like terms which in this case would result in a zero.
8z-8z=0 So the z would be zero or no solution.
Answer:
P= 26
Step-by-step explanation:
Answer:
r = 2.5
Step-by-step explanation:
the area of the whole circle =
*π * 24
A = πr² = (13π*24)/50
r = √((13*24)/50) = 2.5 inches
Answer:
B
Step-by-step explanation:
B
x - 4 squared provides 2 real zeros that are the same. These two are not distinct.
The other two come from x^2 - 7x + 10 which has a discriminate of
sqrt(7^2 - 4*1*10) = sqrt(9) = +/- 3 leading to something real and different.
