now use b²-4ac.
4²-4(1)(4)
16-16
0
If discriminant < 0 there are 2 imaginary solutions
if discriminant > 0 there are 2 real solutions
if discriminant = 0 there is 1 real solution
The discriminant here is 0 so it has one real solution
<span> Percents as decimals are that number divided by 100. The rule is to move the decimal 2 places to the left.
.9
.3
1.159
.09
.07
.65
.003
4.45
edit:
None need to be rounded so do you mean given to the thousandth place? In that case the thousandth is 3 decimal slots places to the left so like this:
.900
.300
1.159
.090
.070
.650
.003

Answer:
60m - 36
Step-by-step explanation:
<em>This equation is asking you what is this quantity times 12? So you distribute the 12 (multiply everything in the quantity by 12)/</em>
(5m - 3)12
12 x 5m = 60m
12 x (-3) = -36
60m - 36
