As we can find that

-8² is -8 x -8  and -7² is -7 x -7

It has the same meaning with rules of positive and negative numbers operation in math :

  • If a negative value timed/divided by a negative value, the result is a positive value.
  • if a positive value timed/divided by a negative value or vice versa, the result is a negative value.

Goryan [66]
Pat's fund earned is $526.40 more than Sam's fund.

Sam's investment :
9400*.052 = 488.80*7 = $3,421.60

Pat's investment :
9400*.06 = 564*7= $3,948.00

$3,948.00-$3,421.60=$562.40

The answer to your question is going to be D. $526.40.

I need to know what goes in each box.<br> :)<br> 20 points
BartSMP [9]

Answer:

3/12 = 4/12

or

3/12 = 1/3

being are last boxes to autofill.

Step-by-step explanation:

1/12 +1/4 = 1/12 + 3/12 = 4.12 = 1/3

When adding the rule of fractions is where required make all denominators the same by dividing the one you want to change to- by the subset one you are changing.

12 / 4 = 3

we get 3/12

Then when adding same denominators 1/12 + 3/12 we just add the top values. = 4/12

The last box would be 4/12 but if asked to simplify we would automatically enter 1/3 for simplification.

As 4/12 = 1/3

When x=-2 and y=-1,-x^2-5xy+5y^3 is
kirill115 [55]

Answer:

-19

Step-by-step explanation:

Evaluate -x^2 - 5 x y + 5 y^3 where x = -2 and y = -1:

-x^2 - 5 x y + 5 y^3 = -(-2)^2 - -2 (-5) + (-1)^3×5

(-2)^2 = 4:

-4 - -5 (-2) + 5×(-1)^3

(-1)^3 = -1:

-4 - -5 (-2) + 5×-1

-5 (-2) = 10:

-4 - 10 - 5

-4 - 10 - 5 = -(4 + 10 + 5):

-(4 + 10 + 5)
