Find the product. 3(x + 4) (x - 5) A. 3x2 ? 20x B. 3x2 ? 11x ? 20 C. 3x2 ? 3x ? 60 D. 3x2 ? x ? 20

Answers

For this case we must find the product of the following expression:3 (x + 4) (x-5)

We must apply distributive property to the terms of the first parenthesis:

(3x + 12) (x-5) =

Again we apply the distributive property:

3x ^ 2-15x + 12x-60 =\n3x ^ 2-3x-60

ANswer:

3x ^ 2-3x-60

Step 1: Distribute the 3 to x and 4

(3x + 12)(x - 5)

Step 2: FOIL (First, Outside, Inside, Last)

Multiply the first of the values in the parentheses together

(3x + 12) (x - 5)

3x^(2)

Multiply the outside values in the parentheses together

(3x + 12)(x - 5)

-15x

Multiply the inside values of the parentheses together

(3x + 12)(x - 5)

12x

Multiply the last values of the parentheses together

(3x + 12)(x - 5)

-60

Step 3: Add all the FOIL values together

3x^(2) + (-15x) + 12x + (-60)

Step 4: Combine like terms

3x^(2) + (-15x) + 12x + (-60)

3x^(2) - 3x - 60

Bob has 3 children, the product of their age is 72, his youngest child called justice, what are their ages

Answers

I have encountered this question before. Since only the product of the ages is given, there are a lot of possible combinations.

3 kids, has a youngest child - means that the 3 kids have different ages.

I performed a prime factorization on 72.

72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 =   9
  9 ÷ 3 =   3
  3 ÷ 3 =   1

1 x 2 x 2 x 2 x 3 x 3 = 72

Possible age combination:

1 x 8 x 9 = 72
2 x 4 x 9 = 72
3 x 4 x 6 = 72
1 x 6 x 12 = 72
1 x 4 x 18 = 72

True or false: Polar equations can describe graphs as functions, even when their equations in the rectangular coordinate system are not functions.

Answers

The statement above is true. Polar equations indeed can describe graphs as functions, even if when the equations in the rectangular coordinate system are not one of the functions. Polar equations can be graphed accurately using hands by using the Polar Coordinate System.

Answer:

The answer is true.

Step-by-step explanation:

A polar equation describes the relation between r and θ. Here 'r' is the distance from the origin to a point curve. 'θ' is the angle made by a point on a curve, the pole, and the positive x-axis.

So, the statement - Polar equations can describe graphs as functions, even when their equations in the rectangular coordinate system are not functions - is true.

If you have budgeted 12% of your monthly income for groceries, how much can you spend on groceries if you earn $950 bi-weekly? A. $190 B. $2,280 C. $114 D. $228

Answers

To calculate this you would need to calculate your monthly income. Because most months are made up of around four weeks you would need to double your $950 bi-weekly (every other week) income because you get paid twice a month. This would result in a monthly income of $1,900. After this you would need to take 12% of that monthly income so multiply $1,900 by 0.12 to come up with D. $228

If you earn $950 bi-weekly, you earn 2 x 950 = $1900 per month. If you have budgeted 12% of your monthly income for groceries you need to find 12% of $1900: (1900 / 100) x 12 = 228. Answer: you can spend $228 a month on groceries.

A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x + 162 square inches.Which could be the dimensions of the rectangular piece of cloth when it is unfolded? Remember, the area of a rectangle can be determined using the formula A = lw.

length = (x + 9) inches and width = (x + 3) inches
length = (x − 3) inches and width = (x − 9) inches
length = (x + 18) inches and width = (x + 9) inches
length = (x − 9) inches and width = (x − 18) inches

Answers

we have

x^(2) + 27x + 162

Using a graph tool------> to resolve the second order equation

the solution is

x=-18\n x=-9

so

x^(2) + 27x + 162=(x+18)*(x+9)

therefore

the answer is the option

length = (x + 18) inches and width = (x + 9) inches

Hello,

(x+9)(x+3=x²+21+27 No
(x-3)(x-9)=x²-12x+27 No

(x+18)(x+9)=x²+27x+162 Yes
(x-9)(x-18)=x²-27x+162 No
