Can u help me ASAP!!!

Answer:

You would distribute the imaginary 1 to 4w cubed and then do the same to the other side as well so 1 times-2w cubed would still be -2w and then 4w cubed would still be 4v  and the answer is: -8v^3w^4

Answer:

Option (A)

Step-by-step explanation:

From the given piecewise function that represent the amount of bill from number of units of electricity used is 'x' kWh.

b(x) = 0.10x   when x ≤ 200

         0.15(x - 200) + 20  when x > 200

For x = 400 kWh,

Function which represents the expenses of the bill,

b(400) = 0.15(400 - 200) + 20 [Since x > 200]

           = 0.15(200) + 20

           = 30 + 20

           = $50

Therefore, Option (A) will be the answer.

Answer:

Step-by-step explanation:

From the picture attached,

There are two parallel lines intersected by three transverse lines.

m∠2 = 98°, m∠3 = 23°, m∠8 = 70°

a). Since ∠1 and ∠2 are linear pairs,

   m∠1 + m∠2 = 180°

   m∠1 + 98° = 180°

   m∠1 = 180 - 98

   m∠1 = 82°

b). m∠4 = m∠7 [Corresponding angles]

   m∠7 = 180° - (m∠2 + m∠3) [Property of a triangle]

            = 180 - (98 + 23)

            = 180 - 121

            = 59°

    m∠4 = m∠7 = 59°

c). m∠5 = 180° - (m∠3 + m∠4)

             = 180° - (23° + 59°)

             = 180° - 82°

             = 98°

d). m∠6 = 180° - (m∠7 + m∠8)

             = 180° - (59° + 70°)

             = 180 - 129

             = 51°

e). m∠7 = 59° [Calculated in part b]

f). m∠9 = 180° - (m∠4 + m∠8) [Property of a triangle]

            = 180° - (59 + 70)°

            = 180 - 129

            = 51°

g). m∠10 = 180° - m∠9

               = 180 - 51

               = 129°

Answer:

3x(3x+2)

Step-by-step explanation:

1. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)

Answer:

Step-by-step explanation:

In this problem, we are told that Delia bought 4.5 pounds of fruit

and paid with a toa total bill of 20+5= 25 bill

and also she received a  change of 3.67

this means that the item she bought cost 25-3.67= 21.33bill

now if 4.5 pounds of items cost 21.33 bill

then 1 pound will cost Xbill

cross multiply and solve for Xbill

X= 21.33/4.5

X= 4.74 bill

One pound of the item will cost 4.74 bill

Answer:

100n+250t

Step-by-step explanation:

cost of the1 one day pass=100

cost of n one day passes=100n

cost of the 1 three day pass=250

cost of t three day passes=250t

Total sale= 100n+250t

The expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Cost of one-day passes, n = $100

Cost of three-day passes, t = $250

So, Total tickets sold = Cost of one-day passes + Cost of three-day passes

⇒ Total tickets sold = n + t

⇒ n + t = $100 + $250

⇒ n + t = $350

which is the required expression for total tickets sold.

Thus, the expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.

Answer:

120 pages can be printed in 1 hour.

Step-by-step explanation:

First divide 36 by 18 to figure out how many pages can be printed in a minute.

Like this: 36 pages ÷ 18 minutes = 2 pages in one minute.

Now, multiply 2 by 60 to figure out how many pages can be printed out in a hour.

Like this: 2 pages in one minute × 60 minutes ( one hour) = 120 pages in one hour can be printed.
