Find the product of (4x + 3y)(4x − 3y).16x2 − 24xy + 9y2
16x2 − 9y2
16x2 + 24xy + 9y2
16x2 + 9y2

Answers

Answer:

Option B is correct

16x^2-9y^2

Step-by-step explanation:

The distributive property says that:

a \cdot (b+c) = a\cdot b+ a\cdot c

To find the product of (4x + 3y)(4x − 3y).

Distribute the first term of the first expression to the second expression and second term of the first expression to the second expression we have;

4x(4x-3y)+3y(4x-3y)

Apply the distributive property;

16x^2-12xy+12xy-9y^2

Combine like terms we have;

16x^2-9y^2

therefore, the product of  (4x + 3y)(4x − 3y) is, 16x^2-9y^2

Answer:

Correct Answer: 16x^2 - 9y^2

Find the probability. Round to nearest tenth.

Answers

Answer:

Probability: (About) 0.8

Step-by-step explanation:

~ Provided that point X is randomly plotted on the line segment JM, we must calulculate the probability with which it lands on KM the first time ( implied ) ~

1. We know that the line segment JM, by the Partition Postulate ⇒ JK + KL + LM. With that being said JM = 3 + 7 + 4 = 14 units

2. Now line segment KM, by the Partition Postulate ⇒ KL + LM. With the assigned values, we can tell that KM = 7 + 4 = 11 units

3. If we were to determine the porbability that X lands on the line segment KM, considering the first try it would be KM/JM ⇒ Probability: 11/14

what is the side length of the largest square tile that can be used to tile a rectangular floor measuring 12 ft by 38 ft if the tiles cannot be cut?

Answers

A square tile 2ft by 2 ft will be used to tile the rectangular floor.

What is a Rectangle ?

A rectangle is a polygon with four sides , The opposite sides of the polygon is equal and parallel.

A rectangular floor has measure of

Length = 12ft

Width = 38 ft

The side of the square tile that can be used to tile the floor is ?

The highest common factor of the rectangular sides 38 and 12 is 2

Therefore a square tile 2ft by 2 ft will be used to tile the rectangular floor.

Eighty-four is what percent of 212? 3.962% 39.62% 2.52% 25.2%

Answers

Answer:

Option B, 39.62%

Step-by-step explanation:

We have to find 84 is what percent of 212.

For this we will put 84 in the numerator and 212 in the denominator to find the fraction first.

Then we will multiply this fraction by 100 to get the percentage.

Fraction of 84 to 212 = (84)/(212)

                                  =  (21)/(53)

Now the percentage will be (21)/(53)* 100

                                        = 39.62%

Option B, 39.62% is the correct answer.

The value of percentage 84 is of 212 is 39.62%, the correct option is B.

We are given that;

Percentage= 84%

Number= 212

Now,

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

To find the percentage, we need to divide 84 by 212 and then multiply by 100.

By solving

84 / 212 = 0.3962

0.3962 x 100 = 39.62

Therefore, by percentage the answer will be 39.62%.
