Answer:
0.069
Step-by-step explanation:
0.3*0.23=0.069
A.
the radicand is b²-4ac
if it is in form ax²+bx+c
when it is
greater than 0, then 2 real roots
equal to 0, then 1 real root
less than 0, then no real roots
so
a=4
b=-12
c=10
b²-4ac=(-12)²-4(4)(10)=144-160<0
so 0 real roots
B.
using quadratic formula because it is easier
for
ax²+bx+c=0
so
for 2x²-13x+21
a=2
b=-13
c=21
x=(13+1)/4 or (13-1)/4
x=14/4 or 12/4
x=7/2 or 3
24 video games.
First you subtract $72 from $1,128 then you divide $43 from $1,056 and you get 24.5581395
So the most video games jasmine can buy is 24.
