What is (3x+12)-(6x+5)

Answer: B i think

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

The equation would first look like 9/-3

When you are dividing negativ numbers a negative divided by a positive is always a negative so 9/-3 is -3

Answer:

The answer is 0. those types of lines NEVER touch

Answer:

x=6/5

Step-by-step explanation:

5x+12=18→ 5x=18-12

5x=6 divide

x=6/5

Answer:

x=6/5

Step-by-step explanation:

(5x+12)=18

5x+12=18

5x=18-12

5x=6

x=6/5

Answer:

Step-by-step explanation:

x2 + 5x + 4  (the area of the rectangle)

x + 2   (the length of one side)

(x2 + 5x + 4)/(x + 2)

do a division of this polynomial and you get;    (x + 3) - 2/(x+2), you could leave the answer like this or you could simplify by using the LCM method

= [(x+2)(x+3) - 2]/(x + 2)

checking; (x + 2)*[(x+2)(x+3) - 2]/(x + 2) = (x+2)(x+3) - 2 = x2 +5x + 6 - 2 = x2 +5x + 4 (proven)

Answer: x = 10

Step-by-step explanation:

8x = 6x +20

2x = 20

X = 10

Check:

8(10) = 6(10) + 20

80 = 60 + 20

80 = 80

Answer:84/5

Step-by-step explanation:dd

Answer:

A. $0.75

Step-by-step explanation:

0.75×2=1.50 (1.50 price of 2 hotdogs)

4-1.50= 2.50 (2.50 is the price of 2 sodas)

1.50 + 2.50= $4

Step-by-step explanation:

Answer:

1: 11√3 - 7√6

2: 11√3 - 7√6

3: -9

4:12

Step-by-step explanation:

To add radicals they need to have the same radical part for the first one we have

7√3- 4√6 + √48 - √54

We can simplify the last two into 4√3 and 3√6

So we have 7√3 - 4√6 + 4√3 - 3√6

adding similar radicals we get

11√3 - 7√6

For the second one we have 11√3 - 7√6

There's nothing we can do from here so keep that as your answer

This one is quite easy -3√9

square root of 9 is 3

so we have -3*3 which is -9

next is

4√9

same deal as the one before

3*4=12

Answer:

Step-by-step explanation:

If 4 less than and is -15 then the following must be true .

n-4= -15

to solve this equation we need to add iv to both side

n-4+4= -15+4

this is simplified to the following

n= -11

Answer:

-r^4+3r^3-21r+49

Step-by-step explanation:

(−r2+3r+−7)(r2+−7)

=(−r^2)(r^2)+(−r^2)(−7)+(3r)(r^2)+(3r)(−7)+(−7)(r^2)+(−7)(−7)

=−r4+7r2+3r3−21r−7r2+49

=−r4+3r3−21r+49

The given polynomial in the standard form is -

- r⁴ + 3r³ - 21r + 49

Given is the following polynomial -

(- r² + 3r - 7)(r² - 7)

We can write the polynomial as -

(- r² + 3r - 7)(r² - 7)

Expanding, we get -

r²(- r² + 3r - 7) - 7(- r² + 3r - 7)

- r⁴ + 3r³ - 7r² + 7r² - 21r + 49

- r⁴ + 3r³ - 21r + 49

Therefore, the given polynomial in the standard form is -

- r⁴ + 3r³ - 21r + 49.

I hope it will helps u

As given

x²-3x-10

Now according to the one of the rule of factorization ,

we have to find such two values whose product becomes equal to the

"product of first and last term " and if we sum those numbers it should be equal to the "middle term of it".

so such numbers are   -5x and +2x

if we add or multiply them we get the above

as  adding    -5x+2x=-3x  (middle term)

also multiplying   -5x*2x=-10x²  (product of 1st and last term)

so now , we can write as,

x²-3x-10

=x²-5x+2x-10

now making groups of 2 terms,

=(x²-5x)+(2x-10)

now common

=x(x-5)+2(x-5)

now common(x-5)

=(x-5)(x+2)   This is the required factors.....

Answer:

What is the question/questions please

Answer:

x=5

Step-by-step explanation:

Given:

The perimeter of a rhombus of side d cm  is

[tex]p=4d[/tex]

To find:

The perimeter of a rhombus of  side 3.2 cm.

Find the length of a side of a rhombus  of perimeter 14 cm.

Solution:

Side of a rhombus is 3.2 cm. So, its perimeter is

[tex]p=4(3.2)[/tex]

[tex]p=12.8[/tex]

Therefore, the perimeter of a rhombus of  side 3.2 cm is 12.8 cm.

The perimeter of another rhombus is 14 cm, and we need find its side.

[tex]p=4d[/tex]

[tex]14=4d[/tex]

Divide both sides by 4.

[tex]\dfrac{14}{4}=d[/tex]

[tex]3.5=d[/tex]

Therefore, the length of a side of a rhombus  of perimeter 14 cm is 3.5 cm.

Answer:

p = 3

q = 4

Step-by-step explanation:

p + 2q  = 11          --------------------(I)

       p = 11 - 2q

2p + q = 10         --------------------(II)

Substitute p = 11 -2q in equation (II)

2(11 - 2q) + q =10

2*11 - 2q *2 + q = 10

22 - 4q + q = 10

  22 - 3q    = 10

         -3q   = 10 - 22

        -3q    = -12

              q = -12/-3

 q = 4

Plugin q = 4 in equation (I)

p + 2q = 11

p + 2*4  = 11

p + 8 = 11

      p = 11 - 8

      p = 3

Answer:

a=1/3

Step-by-step explanation:

from the point on the graph

x=4 and y=8

substitute them into the equation:

y=a(x-2) (2x+4)

you will get

8=a(4-2) (2(4)+4)

8=a(2) (8+4)

8=a(2) (12)

8=2a×12

8=24a

divide both sides by 24

8/24=24a/24

1/3=a or a=1/3

Answer:

90 cm²

Step-by-step explanation:

Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.

Let the area of the other triangle be x. Therefore:

[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]

[tex] \frac{10}{x} = \frac{16}{144} [/tex]

Cross multiply

[tex] 10*144 = 16*x [/tex]

[tex] 1440 = 16x [/tex]

Divide both sides by 16

90 = x

Area of the other polygon = 90 cm²

Answer:

Answer is 90
