Answer:
a x sqrt(7) - 49sqrt(x)
Step-by-step explanation:
sqrt(7x) [ sqrt(x) - 7sqrt(7)]
Distribute
sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)
We know that sqrt(a) sqrt(b)= sqrt(ab)
sqrt(7x^2) - 7sqrt(7^2 *x)
Now lets separate out the perfect squares
sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)
x sqrt(7) - 7*7sqrt(x)
x sqrt(7) - 49sqrt(x)
If it's gradual, it goes up 3,000 every 5 years. So, the answer is A) 86,000
6 x -9 = -54
<span>6 + (-9) = -3
</span>x2<span> - 3x - 54 = 0
</span>
<span>(X + 6 ) (X - 9)
</span>
x2<span> - 3x - 54 = (X + 6 ) (X - 9)
=
6 & -9
</span>
Answer:
if Im correct it should be $8.40
Step-by-step explanation:
why well if you think of breaking down by say 1/4 of 168 all you do is divide 4 which is the whole amount by 0.2 which is the amount the father gave her so 4/0.2= 20 the you take your whole 168 and divide by 20 which the whole number for 0.2 the your answer should be this 168/20= 8.4 which then i assumed it was $8.40 hopefully that is correct hehe
Answer: 31 1/2 acres
Step-by-step explanation:
2 1/4 = 2.25
2.25 * 14 = 31.5
31.5 = 31 2/4
31 2/4 = 31 1/2
