Answer:

  (25/9)x^18·y^6

Step-by-step explanation:

Maybe you want this simplified.

The appropriate rules of exponents are ...

  (a^b)/(a^c) = a^(b-c)

  (a^b)^c = a^(bc)

Step-by-step explanation:

Answer:

A=24m^2

Step-by-step explanation:

to find the area of this figure you can approach it multiple ways, the simplest way is to split it into two rectangles

respectively one 6m by 3m and another 3m by 2m

find the areas of each rectangle and add them both to get the total area of the figure

(6m*3m)+(3m*2m)=(18+6)m^2=24m^2

Answer:

24x+48

Step-by-step explanation:

(3x+6)(8)

=8(3x+6)

=(8*3x)+(8*6)

=24x+48

Answer: 24x + 48

Step-by-step explanation:

The formula to find the are of a rectangle is A=LW. A being the total area, W being the width, or the value on the bottom (8), and L being length how tall the object is (3x+6).

First you must replace L and W, for their given values.

A= (L) (W)

A= (3x+6) (8)

Then, simply simplify by multiplying 3x+6 by 8

You would end up getting 24x + 48

lion runs 50 miles/hour

answer A

Answer:

A. the cheetah is faster by 10 miles

Step-by-step explanation:

If you add the other half hour a lion can run (25 miles) 25+25=50, 60 is greater than 50 by 10.

Answer:

  D)  a = b= 2√2

Step-by-step explanation:

The hypotenuse of an isosceles right triangle is √2 times the side length. This means you have ...

  a√2 = 4

  a = 4/√2 = 4(√2)/2 = 2√2

Of course, the side lengths are the same (as all answer choices show you). The correct choice is ...

  a = 2√2, b = 2√2

Answer:

m∠3 = 105°

Step-by-step explanation:

Line 'l' is parallel to line 'm' and a transversal is intersecting these parallel lines at two distinct points.

m∠3 + m∠6 = 180° [Consecutive interior angles]

Since, ∠6 = 75° [Given]

m∠3 + 75° = 180°

m∠3 = 180 - 75

        = 105°

Therefore, measure of ∠3 is 105°.

In the given diagram, the measure of ∠3 is 105°

From the question,

We are to determine the measure of ∠3

In the diagram, ∠3 and ∠6 are consecutive interior angles

NOTE:

If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary

That is,

∠3 + ∠6 = 180°

From the given information,

∠6 = 75°

Then, we can write that

∠3 + 75° = 180°

∠3 = 180° - 75°

∠3 = 105°

Hence, the measure of ∠3 is 105°

Answer: 12x^6y^3-28x^4y^5+8x^4y^4-4x^3y^4

Step-by-step explanation:

The requierd product of 4x³y³ and (3x³-7xy²+2xy-y) is:

12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

The monomial and the polynomial are given in the question, as follows:

4x³y³ × (3x³-7xy²+2xy-y)

To find the product of the monomial 4x³y³ and the polynomial (3x³-7xy²+2xy-y), we need to multiply each term in the polynomial by the monomial and then add the results.

(4x³y³) × (3x³) = 12x⁶y³

(4x³y³) ×  (-7xy²) = -28x⁴y⁵

(4x³y³) ×  (2xy) = 8x⁴y⁴

(4x³y³) ×  (-y) = -4x³y⁴

⇒ 12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴

Therefore, the product of 4x³y³ and (3x³-7xy²+2xy-y) is:

12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴

Answer:

Number of cinammon = 12

Number of chocolate = 21

Step-by-step explanation:

Given that:

Cost of Cinnamon candle , c = $3.50

Cost of chocolate candle , d = $2.50

Total amount raised, T = $94.50

d = 2c - 3

Total amount = (cost of Cinnamon * number sold) + (cost of chocolate * number sold)

94.50 = (3.50 * c) + (2.50 * (2c-3))

94.50 = 3.50c + 5c - 7.5

94.50 = 8.50c - 7.5

94.50 + 7.5 = 8.50c

102 = 8.50c

c = 102 / 8.50

c = 12

d = 2c - 3

d = 2(12) - 3

d = 24 - 3

d = 21
