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

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:

-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:

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: x = 10

Step-by-step explanation:

8x = 6x +20

2x = 20

X = 10

Check:

8(10) = 6(10) + 20

80 = 60 + 20

80 = 80

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:

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

Answer:

x=6/5

5x=6 divide

x=6/5

Answer:

x=6/5

Step-by-step explanation:

(5x+12)=18

5x+12=18

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

y=-3x+13

Step-by-step explanation:

y-4=-3x+9

3x+y-13=0 this is correct answer

Answer:

x = 2,24 cm

y = 17,96 cm

Step-by-step explanation:

The volume of a cube is:

V = x²*y      where  x is the side of the square base and the height of the cube

V = 90 cm³

And the surface area of the cube is:

S(c)  =  Area of the base (A₁ ) + Lateral area (A₂)

A₁  = x²       and  V = x²*y     then  y = 90/x²

Therefore total cost is:

Cost of the top plus bottom  C₁ =  0,20 * 2 * x²  C₁ = 0,4*x²

Lateral cost (C₂)  is    C₂ = 0,10 * x*y    then  C₂ =  0,10*x ( 90/x²)    C₂ = 9/x

C(x) = 0,4*x² + 9/x

We take derivatives on both sides of the equation to get:

C´(x) = 0,8*x  -  9/x²

C´(x) =  0     0,8*x  - 9/x²  = 0

0,8*x³ - 9  = 0

0,8 * x³  = 9

x³  =  11,25

x = ∛ 11,25

x  =  2,24  cm

And   y  =  90 / 5,01        y  =  17,96 cm

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 is 90
