Multiply 4 by its reciprocal: 1/8x1/4= 1/32.
Answer:
see below
Step-by-step explanation:
1)
set A is already a set of positive odd numbers below 10 so the intersection of the sets is simply {1,3,5,7,9}
2)
this ask, what do sets A,B, and C have in common?
every set has yellow and green so the intersection is
{yellow, green}
Answer:
see below
Step-by-step explanation:
1st: x
2nd: 5x + 8
x(5x + 8) = 36
5x² + 8x = 36
5x² + 8x - 36 = 0
(x - 2)(5x + 18) = 0
(x - 2) = 0
x - 2 = 0
x = 2
1st: x = 2
2nd: 5x + 8 = 5(2) + 8 = 18
(5x + 18) = 0
5x + 18 = 0
5x = -18
x = -3.6
1st: x = -3.6
2nd: 5x + 8 = 5(-3.6) + 8 = -18 + 8 = -10
