Factor the expression completely 6x^2 + 21x - 12​

Answers

Answer 1
Answer:

Answer:3(2−1)(+4)

Step-by-step explanation:

62+2

1−1

6x^{2}+21x-12

6x2+21x−12

3(22+7x−4)

3(2x^{2}+7x-4)

3(2x2+7x−4)

3(22+7−4)

3(2x2+7x−4)

3(22+8−−4)

3(2x2+8x−x−4)

3(22+8−−4)

3(2x^{2}+8x-x-4)

3(2x2+8x−x−4)

3(2(+4)−1(+4))

3(2x(x+4)-1(x+4))

3(2x(x+4)−1(x+4))

3(2(+4)−1(+4))

3(2x(x+4)-1(x+4))

3(2x(x+4)−1(x+4))

3(2−1)(+4)

How do I do x/3-x/9=6 Pls solve with steps

Answers

Answer:

27

Step-by-step explanation:

Hello,

do you agree that

(1)/(3)-(1)/(9)=(3-1)/(9)=(2)/(9)    ?

Then,

we can simplify as below and multiply by 9 both sides and divide by 2

(x)/(3)-(x)/(9)=(2x)/(9)=6\n\n<=> 2x = 54\n\n<=> x = 54/2= 27

Thanks

Can somebody explain y=2x+3 and y intercept please​

Answers

Answer:

see below

Step-by-step explanation:

y=2x+3

This is the slope intercept form of a line

y = mx+b  where m is the slope and b is the y intercept

y = 2x+3

The slope is 2 and the y intercept is 3

The y intercept is where it crosses the y axis ( where x =0)

Yvette is trying to calculate the distance between point C(1, 2) and point D(7, 10). Which of the following expressions will she use? square root of the quantity of 10 minus 2 all squared plus 7 minus 1 all squared square root of the quantity of 10 minus 1 all squared plus 7 minus 2 all squared square root of the quantity of 10 minus 7 all squared plus 2 minus 1 all squared square root of the quantity of 7 minus 10 all squared plus 1 minus 2 all squared

Answers

So this can be solve using the distance formula: D = sqrt [ (x2 – x1)^2 + (y2 – y1)^2] So the expression she should use is: D = sqrt [ (7 – 1)^2 + (10 – 2)^2] Then the answer would be: D = sqrt [ (6)^2 + (8)^2] D = 10

Answer:

square root of the quantity of 10 minus 2 all squared plus 7 minus 1 all squared

Step-by-step explanation:

Solve the equation. Check for extraneous solutions.

assume
if |a|=b
a=b and -a=b

so

9|9-8x|=2x+3
divide both sides by 9
|9-8x|=2/9x+1/3
assume
9-8x=2/9x+1/3 and
-9+8x=2/9x+1/3


9-8x=2/9x+1/3
times 9 both sides
81-72x=2x+3
add 72x both sides
81=74x+3
minus 3
78=74x
divide both sides by 74
39/37=x

other one
-9+8x=2/9x+1/3
multiply both sides by 9
-81+72x=2x+3
minus 2x both sides
-81+70x=3
add 81 to both sides
70x=84
divide boh sides by 70
x=6/5


x=39/37 and 6/5
check

9|9-8(39/37)|=2(39/37)+3
2646/37=189/37
false

9|9-8(6/5)|=2(6/5)+3
351/5=27/5
false

33 POINTS PLZ. Solve the following equations. a) 2x + 8 = x + 25 + 8 b) 3x + 23 = 2x + 59 c) 5 + 12 = 17 d) 2x - 4 = x + 9 e) 5x - 10 = 4x - 12

Answers

Hi there!

a)
2x + 8 = x + 25 + 8
Collect terms

2x + 8 = x + 33
Subtract x

x + 8 = 33
Subtract 8

x = 25


b)
3x + 23 = 2x + 59
Subtract 2x

x + 23 = 59
Subtract 23

x = 26


c)
5 + 12 = 17
This is not an equation, but the sum of 5 and 12 is 17, so it's true.


d)
2x - 4 = x + 9
Subtract x

x - 4 = 9
Add 4.

x = 13


e)
5x - 10 = 4x - 12
Subtract 4x

x - 10 = - 12
Add 10

x = - 2

Could anyone help me understand this problem?"Find the perimeter of the figure, where AC=26, AD=BF, and D is the midpoint of AC. Round your answer to the nearest tenth."

Answers

It seems you will have to use a LOT of trigonometric calculations.
Line AC = 26 
Line AD = 13 = Line DC = 13
Line BF = 13

Angle ABC = Angle GBF = Angle FBH = 55 degrees each

cosine 40 = 13 (Line AD) / Line AE  
Line AE = 13 / 0.76604  = 16.97

tangent 40 = ED / AD = ED / 13
Line ED = 0.8391 * 13 = 10.908

Line DC =13
 
Angle ABC = 55 degrees
tangent(55) = 26 / AB
AB = 26 / 1.4281  = 18.206

Well, that's about half the calculations.
(As I said it's a lot of work).
