(6x+ 3)(6x^2− 8x + 1)

can anyone please show the work on how to get the answer? Thank you :,)

Answer:

90+55+x

145+x=180*

=35

This is a lot of questions-

I did them all on a calculator.

1.)

3x - 4 + 6x = -31

3x + 6x - 4 = -31

9x - 4 = -31

9x = -27

Answer: x= -3

2.)

17 = 3x - 10

3x -10 = 17

-10 = -10

3x = 27

divide both sides by 3

Answer: x= 9

3.)

2x + 6 = 4x - 8

-6 = -6

2x = 4x -14

-4x (both sides)

-2x = -14

divide both sides by -2

Answer: x = 7

4.)

17x - 5(3x - 11) = 41

2x +55 = 41

-55 (both sides)

2x = -14

divide 2 both sides

Answer: x = -7

5.)

5x - (3x - 6) = 18

2x + 6 = 18

-6 both sides

2x = 12

divide both sides by 2

Answer: x = 6

6.)

6x - 3(4 - 5x) = 30

21 - 12 = 30

+12 boh sides

21x = 42

divide both sides by 21

Answer: x = 2

7.)

x - (-5) = 7

x + 5 = 7

-5 both sides

Answer: x = 2

Answer:

Area of original shape: x1

Area of zoomed shaped: x4

Perimeter of original shape: x1

Perimeter of zoomed shaped: x2

Step-by-step explanation:

Since the image is zoomed in by 2, it means that all measurements are doubled. When calculating the area, the zoomed shape had an area 4 times greater than the original shape! With perimeter, instead of the same multiplier, the perimeter of the zoomed shape was only doubled of the original shape.

C. (0, -3)

Step-by-step explanation:

The red point is (-6, -3)

The blue point is (6, -3)

The only answer that fits through the line that those two would make is (0, -3)

Please mark Brainliest! I need it to level up!!

Answer:

-0.375

Step-by-step explanation:

Way one(the harder one):

Let the line which passes through (1,4) and (9,1) be f(x)=kx+b

Sub (1,4) and (9,1) in and we get [tex]\left \{ {{4=1k+b} \atop {1=9k+b}} \right.[/tex]

=> (9k+b)-(k+b)=1-4

                   8k=-3

                     k=-3/8 or -0.375

Therefore the slope of the line is -3/8 or -0.375

Way two(the easier one):

k= [tex]\frac{change in y}{change in x}[/tex] = [tex]\frac{1-4}{9-1}[/tex] = -[tex]\frac{3}{8}[/tex]

Answer:

rs 28500

Step-by-step explanation:

If she saves rs3420 and spends 88% we need to convert 88% to a decimal first.

88% = 88/100 = .88

Let m equal her monthly income.

m - .88m = 3420

.12m = 3420

.12m/.12  = 3420/.12

m =  3420/.12

m = 28500

He monthly income is rs28500.

Answer:

$10.55

Step-by-step explanation:

Total miles traveled = 12miles

If taxi A charges $0.3 for every 1/9 mile, then for 12 Miles, he will charge;

12×0.3/(1/9)

= 12×0.3×9

= 108×0.3

= $32.4

Amount charged initially = $3.00

Total charge by Taxi A = $32.4+$3.00

Total charge by Taxi A = $35.4

If taxi B charges $0.2 for every 1/9 mile, then for 12 Miles, he will charge;

12×0.2/(1/9)

= 12×0.2×9

= 108×0.2

= $21.6

Amount charged initially = $3.25

Total charge by Taxi B = $21.6+$3.25

Total charge by Taxi B = $24.85

Total money saved by Kelly = Amount charged by Taxi A - Amount charged by Taxi B

Total money saved by Kelly = $35.4-$24.85

= $10.55

Hence Kelly saved $10.55 using taxi B

The answer is 14

Step-by-step explanation:

Answer:

x= 3

Step-by-step explanation:

1. -5(3) + 2 = -13      

2. -15 + 2 = -13         A positive times a negative will always equal a negative

3. -13 = -13         Whenever you add anything to a negative number, the                    

                           number becomes smaller  

                     Ex:  -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, ...........

                           Although the number itself becomes smaller, its value    

                            becomes bigger      

Hope this helps.

Answer:

12

Step-by-step explanation:

Answer:

The expression is equal to 12.

Step-by-step explanation:

[tex]-24-(18 / 6)*(-12)[/tex]

First of all, compute the parenthesis.

18 / 6 = 3

Now, replace 18/6 with 3 in our expression.

[tex]-24-(18 / 6)*(-12)[/tex]

[tex]-24-(3)*(-12)[/tex]

Next, compute the multiplication.

-12 * 3 = -36

Again, we'll replace that multiplication with negative 36:

[tex]-24-(3)*(-12)[/tex]

[tex]-24-(-36)[/tex]

Since subtracting a negative number is the same as adding a positive number:

[tex]-24-(-36) = -24+36[/tex]

Compute the addition:

[tex]-24+36=12[/tex]

[tex]-24-(18 / 6)*(-12) = 12[/tex]

Answer: The expression is equal to 12.

Answer:

Because 6X will cancel out, leaving you with no x. And 3 does not equal -5.

Step-by-step explanation:

6X + 3 = 6X -5

-6X         -6X

   3= -5 (not true)

Answer:

He will need 20 3-inch blue tiles

Step-by-step explanation:

Here, the total space to fill is a length of 5.75 ft

The tiles to place at the center has 3/4 ft which is same as 0.75 ft

The length left unfilled will be 5.75 - 0.75 = 5 ft

Now we want to know the number of 3 ft tiles needed to fill up this length;

Mathematically, we know that

1 ft = 12 inches

So 5 ft will be 5 * 12 = 60 inches

So the number of 3 inch tiles needed to fill this length will be 60/3 = 20 tiles

Answer:

Jack's birthday is in 56 days.

The jumps end at point 56 on the number line.

Step-by-step explanation:

Since one week has 7 days.

So, 8 week = 8 x 7 =56 days.

Hence, Jack's birthday is in 56 days.

On the number line, the current time is being represented by 0.

When I take one jump from 0, I will reach the point 1 on the number line, which corresponds to 1 day.

Again, in my 2nd jump from point 1 on the number line, the next point on the number line will be 2 which corresponds to 2 days.

This process repeats until I complete the 56 jumps to get point 56 on the number line, which corresponds to 56 days.

In this way, the number line can be used to solve.

Hence, the jumps end at point 56 on the number line.

Answer:

3f + 5²

Step-by-step explanation:

3 times a number f means we could just put them together, aka 3f. Then increased means we can add. Next you see 5 squared. Squared means the exponent is 2, or you are multiplying the number with itself.

Answer:

The angle of rotation pf a six sided star, that will carry the six sided star onto itself is 60°

Step-by-step explanation:

The angle of rotation that will carry a six sided star onto itself is the angle between two adjacent lines of symmetry of the six sided star

Given that there are three lines of symmetry of the six sided star, and each line intersect with the next line at the center of the figure, the angle between two adjacent lines of symmetry = 360°/(2 × 3) = 60°

Therefore, the angle of rotation pf a six sided star, that will carry the six sided star onto itself = 60°.
