Answer:

The answer is option D

Step-by-step explanation:

When factored out option C and D are the same but it is a perfect square, not the difference of squares.

Option (D) 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial is the correct answer.

An expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Algebraic expressions include at least one variable and at least one operation.

For the given situation,

The expression is (4xy-3z)^2.

This expression can be expand by using the formula,

[tex](a-b)^{2} = a^{2} -2ab+b^{2}[/tex]

Here, a = 4xy and b = 3z

⇒ [tex](4xy)^{2} -2(4xy)(3z)+(3z)^{2}[/tex]

⇒ [tex]16x^{2} y^{2} -24xyz+9z^{2}[/tex]

Hence we can conclude that option (D) 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial is the correct answer.

Answer:

131.2 ;

12.8 ;

(118.4, 144)

Step-by-step explanation:

Given :

X = 131.2, s=55 , and n= 50

Point estimate of the mean :

Since, sample size is large (n > 30) ; the sample mean = population mean according to the center limit theorem :

Margin of Error = Zcritical * s / sqrt(n)

Zcritical at 90% = 1.645

Margin of Error : 1.645 * (55 / sqrt(50))

Margin of Error : 1.645 * 7.7781745

Margin of Error = 12.795097

Margin of Error = 12.8

The confidence interval (C.I) :

C.I = x ± margin of error

C. I = 131.2 ± 12.8

(131.2 - 12.8) ; (131.2 + 12.8)

Answer:

2x+4

Step-by-step explanation:

remember the formula (a+b)^2=a^2+b^2+2ab

in this case, 4x^2 would be a^2, 16 would be b^2, and 16x would be 2ab

so, the variable a would be 2x and the variable b would be 4

so, you can turn 4x^2+16x+16 into (2x+4)^2

and since the area of a square is (one of its sides)^2, or in this case (2x+4)^2, the length of one side of the lawn will be 2x+4

problems where you have to use the (a+b)^2=a^2+b^2+2ab formula to turn trinomials into binomials squared are very common, so make sure to look out for questions like these and be ready to use this formula

In the diagram above is a 2 right angle triangles

the length of such diagrams is found using the pythagoras theorem.

in finding the length of the vertical by pythagoras gives..(13²-5²)^-2=12

Answer:

Yes/True

Step-by-step explanation:

The given expression is :

y = 12 x

We know that, Proportional means it has an equivalent ratio / constant rate of change / the same rate.

Here,

y ∝ x

12 is the constant of proportionality

Hence, the given expression is proportional.

Answer: Choice A) 5x^3 - x - 3

=================================================

Work Shown:

We subtract the two functions like so

(f - g)(x) = f(x) - g(x)

(f - g)(x) = ( 5x^3-2 ) - ( x+1 )

(f - g)(x) = 5x^3 - 2 - x - 1

(f - g)(x) = 5x^3 - x - 3 ..... choice A

Note: be sure to remember to distribute the negative to every term inside (x+1), and not just to the x only.

Answer:

20

Step-by-step explanation:

when you subtract 2 from 6 you get 4. so you multiply 4 into 2 which give the answer 8. when you subtract 2 from 8 you get 6 and then you multiply 6 to 2 which gives the answer 12... next you subtract 2 from 12 which gives the answer 10. so you multiply 10 to 2 Which gives the final answer for you which is 20.

Mr. Mann asked his class to form a number pattern using the rules:

Use the number 6 as the first term.

To find the other term, subtract 2 from the previous term, then multiply by 2.

The first two numbers in the pattern are 6 and 8.

What is the fourth number in the pattern?
