Let's check the distributive property first :
where ,
, and
are real numbers.
Now, to express 4x24 in the form , we just need to express 24 as a sum or subtraction.
Notice that we can express a 24 as a sum or subtraction in a number of ways:
1. 24-12=12, so 12+12=24
2. 24-10=14, so 10+14=24
3. 28-4=24, so 28-4=24
And so on...
Now let's use the distributive property:
1.
Since 24=12+12, we can express the same multiplication using the distributive property as:
2.
Since 24=10+14, we can express the same multiplication using the distributive property as:
3.
Since 24=28-4, we can express the same multiplication using the distributive property as:
As you can see, there are many ways to use the distributive property.

in form ax²+bx+c=0
when b²-4ac>0, it has 2 real roots
when b²-4ac=0, it has 1 real root
when b²-4ac<0, it has no real roots
so
we solve for no real roots
b²-4ac<0
a=3
c=7
b=-m
(-m)²-(4)(3)(7)<0
m²-84<0
add 84 both sides
m²<84
sqrt both sides
m<9.1 about
nearest integer
round down
m=9
answer is m=9

45 = 15% × n
15% =
45 = 0.15n
0.15 and 0.15 cancels out
300 = n
15% of 300 is 45
45 is 155 of 300
15% × x = 45
x = 45 ÷ 15%
x = 45 ÷ 15/100
x = 45 × 100/15
x = 4500/15
x = 300
Check:
15% × 300
= 15/100 × 300
= 15 × 3
= 45
45 is 15% of 300.
