Answer:

Ann makes $252 this week

Step-by-step explanation:

To find the amount she made in total, mutliply the rates by the amount of hours she worked at that rate. Start with the weekday rate.

$8 * 24 = $192

Now do the weekend rate

$10 * 16 = $160

Now add the two amounts together

$192 + $160 = $252

Zack has been planting young trees in his garden. The maple tree that is 42 inches tall is growing 1 inch per month, whereas the
kolezko [41]

In 16 months, two trees will be of same height

The trees will be of 58 inches tall

<em><u>Solution:</u></em>

Let "x" be the number of months

<em><u>The maple tree that is 42 inches tall is growing 1 inch per month</u></em>

Thus, equation for maple tree is given as:

Maple tree : 42 + 1 inch (number of months)

Maple tree : 42 + x ------- eqn 1

<em><u>The oak tree that is 10 inches tall is growing 3 inches per month</u></em>

Thus, equation for oak tree is given as:

Oak tree : 10 + 3 inch (number of months)

Oak tree : 10 + 3x -------- eqn 1

<em><u>For two two trees to be equal in height, equate eqn 1 and eqn 2</u></em>

42 + x = 10 + 3x\\\\3x - x = 42 - 10\\\\2x = 32\\\\x = 16

Thus, in 16 months, two trees will be of same height

<em><u>What will that height be?</u></em>

Substitute x = 16 in any one eqn

10+3x = 10 + 3(16) = 10+48 = 58

Thus the trees will be of 58 inches tall

The side length, s, of a cube is x – 2y. If V = s3, what is the volume of the cube? x3 – 6x2y + 12xy2 – 8y3 x3 + 6x2y + 12xy2 +
otez555 [7]

V = x³ - 6x²y + 12xy² - 8y³

V = (x - 2y)³

   = (x - 2y)(x - 2y)(x - 2y) ( expand first pair of factors )

   = (x² - 4xy + 4y²)(x - 2y) ( multiply terms in first by terms in second )

   = x³ - 4x²y + 4xy² - 2x²y + 8xy² - 8y³ ( collect like terms )

  = x³ - 6x²y + 12xy² - 8y³
