COULD A KIND SOUL PLEASE HELP ME OUT?????!!!!!!!!!!!!!!!

In the triangle shown ,AB =2x +9 and BC=5x–12. Find the value of x.

show how you go the answer so I can see if it makes sense!!!

Answer:

6

Step-by-step explanation:

f(x)=2x^3-5x when x=2. So f(2)=6

Answer:

8

Step-by-step explanation:

-2 xy

Let x = -4 and y = 1

-2 (-4)*(1)

8(1)

8

Explanation:

Point F is located at (2,0)

Multiply each of those coordinates by the scale factor 2.5

This means point F(2,0) moves to F ' (5,0) after applying the dilation, where the dilation is centered at the origin.

Answer: 320

Step-by-step explanation:

Step 1) Identify Number of options for each set

For the entree, you have 4 options, for the sides, you have 4 options, and for the drink you have 5

Step 2) Find all possible outcomes

4 options for the entree × 4 options for the first side × 4 options for the second side × 5 options for the drink

Step 3) Solve

4 × 4 × 4 × 5 = 320

Answer:

$31.5

Step-by-step explanation:

Intrest = P. A. * Intrest Rate * Time

Intrest = 600 * 5.25 /100 = 31.5

Answer:

540

Step-by-step explanation:

546-56=490

490+17+30=537

537+3=540

Answer:

okay so given :-

R = x(A+B)

now open bracket =>

R = Ax + Bx

shifting Bx

R - Bx = Ax

so now shift x to lhs and finally we get

A = (R - Bx)/x option d is correct

please brainliest <3

Step-by-step explanation:

A=3B

A+B=36

3B+B=36

4B=36

B=36/4

Step-by-step explanation:

let x represent the smaller number

3x is the second number

x+3x=36

4x=36

4x/4=36/4

x=9

the second number is 3(9)

=27

Answer:

87.965

Step-by-step explanation:

surface area of a cylinder,

2πr²+2πrh (where r = radius, h = height)

given, h = 5, r = 2

so,

2πr²+2πrh

= 2π×2²+2π×2×5

= 8π+20π

= 28π

= 87.9645943..

= 87.965 (rounded to the nearest thousand)

Answer:

Answer is -6t

Step-by-step explanation:

[tex]{ \tt{ = (6 \cos(20\pi t) \cos(\pi) + 6\sin(20\pi t) \sin(\pi) ) + 6 \sqrt{3} ( \cos(20\pi t) \cos( \frac{\pi}{2} ) + \sin(20\pi t) \sin( \frac{\pi}{2} )) }} \\ = { \tt{ (- 6t + 0) + (0 + 0)}} \\ = { \tt{ - 6t}}[/tex]

Note that π is 180°

Answer

28,800$

Step-by-step explanation:

480 x 4 = 1920 x 3 = 5760 x 5 = 28800

Answer:

88 ft^3

Step-by-step explanation:

First find the volume of the rectangular prism on the left

V = l*w*h = 2*(4)*8 = 2*4*8= 64 ft^3

Then find the volume of the rectangular prism on the bottom

The base is not 5 but 5-2 since we used 2 on the left side

V = l*w*h = (5-2) *4*2 = 3*4*2 = 24 ft^3

Add them together

64+24=88

Answer:The right answer is B

Step-by-step explanation:

If it's negative then it should be on the other side with one side down on the graph and one side on the left.(hope this helped you) :)

Answer:

x = 2

Step-by-step explanation:

Answer:

(c) 9 3/5

Step-by-step explanation:

This is a ratio question. We can work with the dimensions as fractions and solve through cross-multiplication.

Dimensions of the first painting:

8/20 in.

Possible dimensions of the second painting:

24/x in.

x/24 in.

There are two options, because the given 24 inches may be either a length or width of the painting.

Now, we can use cross-multiplication to try to find x in both scenarios.

Scenario #1

8/20=24/x

8x=480

x=60 in.

60 in. is not an answer. Let's try the other scenario.

Scenario #2

8/20=x/24

192=20x

9.6 in.=x

9.6 can also be written as 9 3/5, which is option C.

Answer:

9

Step-by-step explanation:

Plug in 2 for x

You should get f(2)=(2+1)^2

Add 2+1 inside the parenthesis to get 3

Finally do (3)^2 to get 9

D

Step-by-step explanation:

Change=Temperature/Time

Change=(-49/4)/(7/2)

Answer:

-24

Step-by-step explanation:

m(4)=2*4^2-10*4-14=-22

m(-1)=2*(-1)^2-10(-1)-14=-2

m(4)+m(-1)=-24

Answer:

Step-by-step explanation:

Subtract 4x from both sides

4x-4x + 2y = -4x - 12

2y = - 4x - 12            

Divide by 2

2y/2 = -4x/2 - 12/2

y = -2x - 6

The y intercept happens when x = 0

y intercept is - 6

or 0,-6

Answer:

y intercept = -6

x intercept = -3

Step-by-step explanation:

Answer:

(base x height x length)/2 = volume

6x8x8 = 384/2 = 192in^3

hope that answers your question

Answer:

C

because if you arrange orderly ie in an ascending order or a descending order,the middle number is the median and median means average

Write the area A of an equilateral triangle as a function of the length s of its sides. Draw the triangle; label each side "2s". Draw the altitute; it will bisect the base into s and s. ... Therefore, the area is equal to the measure of the bisected side times the measure of the altitude, quantity divided by 2.

HOPE SO IT HELPS YOU

Answer:

Step-by-step explanation:

Part A

Each side including     the base is s.

Part B

Use 1/2 the base to find the height. The height meets the base at 90 degrees which gives you the right to use c^2 = b^2 + a^2

The hypotenuse is s

The base is 1/2s

h^2 = s^2 - (1/2s)^2

h^2 = s^2 - 1/4 s^2

h^2 = 3s^2/4

h = sqrt(3)/2 *s

Area = 1/2 * s * sqrt(3)/2 s

Area = 1/4 * s^2 * sqrt(3)

Answer:

see below

Step-by-step explanation:

It is given that m<A +m<B = m<B + m<C.  We can subtract angle B from each side using the subtraction property of equality.  That leaves m<A = m<C  We can use the symmetric property so that m<C = m<A
