Answer:
A)
Step-by-step explanation:
We know that the expression (x^2 - a^2) can be written as (x-a)(x+a). So an expression of this type: (x^2 - a^2) wouldn't be completely factored because it could be factorized even more.
So we know that 36 = 6^2, 49= 7^2 and 81 = 9^2. So if we choose any of these options (Option B, C and D) it wouldn't be completely factored.
The correct is the option A, given that if a=12, it wouldn't be a perfect square, so it would be completely factored.

Answer:
6 miles
Step-by-step explanation:
From the above question:
Stan ran 4 and StartFraction 7 Over 10 EndFraction miles
The number of miles stan ran =
4 7/10 miles
We are also told that this number of miles was 1 and StartFraction 3 Over 10 EndFraction fewer miles than Matt ran.
Let the number of miles Matt ran = m
Hence,
4 7/10 miles = m - 1 3/10
m = 4 7/10 + 1 3/10
m = (4 + 1) + ( 7/10 + 3/10)
m = 5 + (7 + 3/10)
m = 5 + (10/10)
m = 5 + 1
m = 6 miles
Therefore, the number rod miles Matt ran was 6 miles
Answer:
y = m/3
Step-by-step explanation:
y 1
---- = --------
m 3
Cross multiply
3*y = 1*m
3y = m
Divide each side by 3
3y/3 = m/3
y = m/3
$4.30X40%=1.72
4.30-1.72=2.58
2.58X6%=.15
2.58+.15=2.73
Final price: $2.73
