(6p + 4q)(-2p + 9q) simplify please help me with this

Answers

Answer 1

Answer: $(6p + 4q)(-2p + 9q) =\n \n=-2p\cdot 6p + 9q\cdot 6p -2p\cdot 4q + 9q\cdot 4q=\n \n=-12p^(2)+54pq-8pq+36q^2=\n \n =-12p^(2)+46pq +36q^2$

Answer 2

Answer: Well first you have to multiply using FOIL, so...
-12p² + 54qp -8qp +36q²
-12p² + 46qp + 36q² is the simplified answer
Hope that helps :)

3-3x6+2= -13 ? Is that correct

Answers

If x is a sign of multiplication, then 3-3x6+2 = -13 is incorrect.

The order of mathematical operation is PEMDAS.

1st operation to perform is the numbers inside a PARENTHESIS
2nd operation to perform is the number with EXPONENTS
3rd operation to perform is MULTIPLICATION
4th operation to perform is DIVISION
5th operation to perform is ADDITION
6th operation to perform is SUBTRACTION.

3-3x6+2 = -13

operation present are multipication, addition, and subtraction.

3-3x6+2 = -13

first, do multiplication : 3 - 18 + 2 = -13
second, do addition: 3 - 20 = -13
third, do subtraction: -17 = -13 ANSWERS ARE NOT EQUAL. THUS, INCORRECT.

No. Add before you subtract.
3x6 = 18 Multiply first
18+2=20 Addition
3-20= -17 Subtraction is last
-17 is answer

In the figure below, hln. Find the values of z and y.

Answers

To find y:

$3y-14=180$

$3y=194$

$y=64.7$

To find z:

$180 - 64.7 = z$

$z = 115.3$

F(x) 5,450(1.024)^x The domain for the function that represents the amount of time the money will be in the college fund is _ the range for the function that represents the amount of money that is in the college fund is _

Answers

Answer:

1.) Domain X = all positive real numbers

2.) Range: F(x) > = 5450

Step-by-step explanation:

Given that

F(x) = 5,450(1.024)^x

Where the domain is the independent variable X and the range is the dependent variable Y or F(x)

Since the domain for the function represents the amount of time the money will be in the college fund, time cannot be negative, it will always be positive.

Therefore, domain x will be all positive real numbers.

The least domain x = 0

Substituting domain into the equation will give us a range of value:

F(x) = 5450 × ( 1.024 )^0

F(x) = 5450 × 1

F(x) = 5450

That is, the least value of range = 5450

Therefore, Range will be F(x) greater than or equal to 5450.

F(x) > = 5450
