Answer:

8x² - 27x + 20

Step-by-step explanation:

Given

4x(2x - 3) - 5(3x - 4) ← distribute both parenthesis

= 8x² - 12x - 15x + 20 ← collect like terms

= 8x² - 27x + 20 ← in standard form

Answer:

-19x+20

Step-by-step explanation:

So we need to simplify this the first step is

4x(2x-3)  The first part of the equation

4x(2x) - 4x(3)

8x -12x

-4x

then the second part

-5 (3x-4)

-5(3x)+20

-15x+20

add togeter

-4x-15x

-19x

-19x+20

Answer:

m∠SQV + m∠VQT = 180°

Step-by-step explanation:

right on test.

Going from f(x) = x to g(x) = f(x-6) = x-6 will move the graph 6 units to the right.

Effectively replacing x with x-6 shifts the xy axis 6 units to the left, giving the illusion the function curve shifts 6 units to the right.

Answer:

5 > x

Step-by-step explanation:

2(3x - 5) < 4x

~Distribute left side

6x - 10 < 4x

~Subtract 6x to both sides

-10 < -2x

~Divide -2 to both sides

5 > x

Best of Luck!

Answer:

No; equation

Step-by-step explanation:

2x+5 = 10 is not an expression rather it's an equation because it has an equal sign. An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

Answer:

candy 7

packs 5

Step-by-step explanation:

Answer:

Option A!

Step-by-step explanation:

Hey there!

To figure out the ratio of candies per packs, we divide 21 (candy) by packs (3) and we get 7. This means that there are 7 candies per pack! So, in 1 pack, there are 7 candies and when there are 35 candies, we divide 35 by 7 and get 5.

So, in one pack there are 7 candies and there are 35 candies in 5 packs.

Option A. Candy: 7 Packs:5

Am i right? :o

Answer:

B

Step-by-step explanation:

(6[tex]x^{5}[/tex]z)^3

6^3 is 226

*(x^2)^3=  x^6        (5*3= 15)

*when there are exponents being raised to a power, the exponents are multiplied

**(z^1)^3= z^3     (3*1= 3)

** all numbers are raised to the 1st power (unless otherwise noted x^2, 5^4 2^2, etc)

So the top would end up being 226x^6z^3

Now, since this number is over 4x^4z^2,  you need to divide 226x^15z^3 by 4x^4z^2

**divide like terms**

226/4= 54

***x^15/ x^4= x^x^11

*** when you divide exponents, you subtract the bottom number from the top, in this case:

15-4

that equalls 11

So x^11

you do the same for z:

z^3/z^2= z^1 or z      (3-2=1 )

You put it all together and you end up with

54x^11z

Answer:

Side length of each booth is 8.35 ft approximately.

Step-by-step explanation:

There are 11 companies set up equal sized square booths in a row along one wall of a convention center.

Now, refer the diagram to answer the problem.

It is given area is 1200.

So, length x width =1200

(11x+24)(x+2)=1200

Multiply using FOIL method.

[tex]11x^{2}[/tex]+22x+24x+48=1200

[tex]11x^{2}[/tex]+46x+48-1200=0

[tex]11x^{2}[/tex]+46x-1152=0

Solve using quadratic formula

x=[tex]\frac{-46+/- \sqrt{46^{2}-4(11)(-1152 } }{2(11)}[/tex]

x=[tex]\frac{-46+/-\sqrt{2116+50688} }{22}[/tex]

x=[tex]\frac{-46+/-\sqrt{52804} }{22}[/tex]

Simplify it

[tex]x=\frac{-49+/- 229.79}{22}[/tex]

Simplify to get two values for x.

x=8.35; x=-12.67

Here negative does not work.

Side length of each booth is 8.35 ft.
