<h3>Answer:   12i*sqrt(2)</h3>

where i = sqrt(-1)

======================================

Explanation:

The goal is to find the largest perfect square factor so we can then use the rules shown below

  • sqrt(xy) = sqrt(x)*sqrt(y)
  • sqrt(x^2) = x where x is nonnegative

So we have these steps

sqrt(-288) = sqrt(-1*144*2)

sqrt(-288) = sqrt(-1)*sqrt(144)*sqrt(2) .... use rule 1 above

sqrt(-288) = i*12*sqrt(2) ... use rule 2 and i = sqrt(-1)

sqrt(-288) = 12i*sqrt(2)

Answer:

  -31/15

Step-by-step explanation:

Put the numbers in the expression and do the arithmetic.

  c-4x=-\dfrac{7}{15}-4\cdot\dfrac{2}{5}=-\left(\dfrac{7}{15}+\dfrac{8}{5}\right)\\\\=-\left(\dfrac{7}{15}+\dfrac{24}{15}\right)=\boxed{-\dfrac{31}{15}}

jess has $22 and saves $5 each week rosie has $10 and saves $8 each week how many weeks till they have the same amount of money
Lemur [1.5K]
Answer: 5 weeks

Explanation:
Jess starts with $22 and saves $5 per week, Rosie has $10 and saves $8 per week.

In order to find an equal amount of money between the two girls is by finding a common denominator.

Jess- 22, 27, 32, 37, 42
Rosie- 10, 18, 26, 34, 42

Since we found that they can both end up with $42, after a certain amount of weeks have passed, now you’ll want to count how many numbers are in each row to find the amount of weeks it took to get to an equal amount
