I need help with geometry it’s urgent. I will fail class if I don’t pass this test.

Answer:

20²-(13²-5² )=y²

400-(169-25)=y²

400-144 =y²

256=y²

y=16

Step-by-step explanation:

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:

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.

I can't see pictures, but I'm assuming you want it solved.

x+2>7.

Cancel out the 2 by subtracting 2 from both sides.

x+2>7

 -2   -2

x>5

So the inequality is x>5.

Answer:

SA = 384 in²

Step-by-step explanation:

Assuming we're finding surface area:

SA of top of large cube: 8(8) - 4(4) = 48 in²

SA of sides of large cube: 4(8)(8) = 256 in²

SA of exposed faces of small cube: 5(4)(4) = 80 in²

Total = 48 + 256 + 80 = 384 = ∑SA

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:

48 and 5%; 40 and 8%

Step-by-step explanation:

The computation of the difference between the percentage increase for each town from 2016 to 2017 is given below:

Year Ogdenville North Haverbrook

2016              960                500

2017              1008               540

So here the difference would be

For 2016 to 2017

= 1008 - 960

= 48

The percentage increase is

= 48 ÷ 960

= 5%

And,

= 540 - 500

= 40

And, the percentage increase is

= 40 ÷ 500

= 8%

Answer:

It's the first answer. 40

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:

The answer is C x=15

Step-by-step explanation:

Simplify both sides of the equation.

2(x−2)=26

(2)(x)+(2)(−2)=26(Distribute)

2x+−4=26

2x−4=26

Add 4 to both sides.

2x−4+4=26+4

2x=30

Divide both sides by 2.

2x /2  =  30/ 2

Answer:

when distributing the first equation 1/4(8y+24) it is actually 2y+6 because 1/4*24= 6 not 8

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

you want to set it up like this

8/20   and   6/2x-1

then you cross multiply

so 8(2x-1)  = 16x-8

and 20*6 = 120

then you do 120= 16x-8

add 8 to both sides   (you want x by it's self so to get rid of a -8 you have to add 8)

128= 16x  

(divide both sides by 16)

128/16= 8

8=x
