The two triangles below are similar. What
is the perimeter of triangle XYZ?

Answer:

I think is −  

2

3(9y+52)

Step-by-step explanation:

Answer:

The only thing you will do is to plug the x in the equation.

x = -2 ---> f(x) = -6

x = 0 ---> f(x) = 0

x = 3 ---> f(x) = 9

x = 7 ---> f(x) = 21

f(x) = 3x

f(-2) = 3(-2)

f(-2) = -6

f(0) = 3(0)

f(0) = 0

f(3) = 3(3)

f(3) = 9

21 = 3x

21 / 3 = 3x / 3

7 = x

Hope this helps, thank you :) !!

Answer:

a)[tex]x^{2}[/tex]+8x+15

b)[tex]x^{2}[/tex]-x-20

Step-by-step explanation:

a) (x+3)(x+5)

a)[tex]x^{2}[/tex]+5x+3x+15

a)[tex]x^{2}[/tex]+8x+15

b) (x+4)(x-5)

b) [tex]x^{2}[/tex]-5x+4x-20

b)[tex]x^{2}[/tex]-x-20

Answer:

b has 79,775 million

a has 241,275 million

Step-by-step explanation:

a has more than b

b+161,500 is a

b=b

b+b+161,500=321,050

2b=321,050-161,500

2b=159,550

b=159,550/2

b=79,775

a=b+161,500

a=79,775+161,500

a=241,275

Answer:

(sqrt(7))/3 or decimal 0.8819171036881968635005385845464201419034197276941500601227781530...

Step-by-step explanation:

Simplify the following:

(sqrt(14))/(sqrt(18))

Hint: | Simplify radicals.

sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):

(sqrt(14))/(3 sqrt(2))

Hint: | Multiply numerator and denominator of (sqrt(14))/(3 sqrt(2)) by sqrt(2).

Rationalize the denominator. (sqrt(14))/(3 sqrt(2)) = (sqrt(14))/(3 sqrt(2))×(sqrt(2))/(sqrt(2)) = (sqrt(14) sqrt(2))/(3×2):

(sqrt(14) sqrt(2))/(3×2)

Hint: | Multiply 3 and 2 together.

3×2 = 6:

(sqrt(14) sqrt(2))/6

Hint: | For a>=0, sqrt(a) sqrt(b) = sqrt(a b). Apply this to sqrt(14) sqrt(2).

sqrt(14) sqrt(2) = sqrt(14×2):

(sqrt(14×2))/6

Hint: | Multiply 14 and 2 together.

14×2 = 28:

(sqrt(28))/6

Hint: | Simplify radicals.

sqrt(28) = sqrt(2^2×7) = 2 sqrt(7):

(2 sqrt(7))/6

Hint: | In (2 sqrt(7))/6, divide 6 in the denominator by 2 in the numerator.

Answer:  (sqrt(7))/3

Answer:

The slope of the tangent m = -0.0833

Step-by-step explanation:

Step(i):-

Given that the curve

      x y - 2y² + x² = -5 ...(i)

Differentiating equation (i) with respective to 'x', we get

  [tex]x(\frac{dy}{dx} )+y (1) -2(2y)\frac{dy}{dx} + 2x=0[/tex]

    [tex]x(\frac{dy}{dx} ) -2(2y)\frac{dy}{dx} = -2x-y[/tex]

    [tex](x -4y)\frac{dy}{dx} = -2x-y[/tex]

       [tex]\frac{dy}{dx} = \frac{-2x-y}{x-4y}[/tex]

Step(ii):-

The slope of the tangent

[tex](\frac{dy}{dx})_{1,-1.5} = \frac{-2x-y}{x-4y}[/tex]

[tex](\frac{dy}{dx})_{1,-1.5} = \frac{-2(1)-(-1.5)}{1-4(-1.5)}[/tex]

       m =   [tex]\frac{-2+1.5}{1+6}[/tex]

       [tex]m = \frac{-0.5}{6} = -0.083[/tex]

The slope of the tangent m = -0.0833

Answer:

x = 14

y = 40

Step-by-step explanation:

3y+8 = 128

3y = 120

y = 40

45/20=2.25 (scale factor)

5x-25 = 2.25(2x-8)

5x-25 = 4.5x - 18

.5x = 7

x=14

Answer:

33

Step-by-step explanation:

46/22=46+23/x

46x=22 times 69

46x=1518

x=33

Answer:

-8.2,-2.5,.4,2.4

Step-by-step explanation:

start by negatives. negatives are lesser the higher they are. so -8.2 is less than -2.5. then positives are greater than negatives. .4 is less than 2.4. hope this helps

Answer:

The option of 6 minutes with 8 tickets given more time for the money.

Step-by-step explanation:

Which one gives you more time for your money?

We have to find the time per ticket, which is the number of minutes divided by the number of tickets.

6 minutes: 8 tickets

6/8 = 0.(60/8) = 0.75 minutes per ticket.

8 minutes:12 tickets

8/12 = 2/3 = 0.(20/3) = 0.667 minutes per ticket.

So the option of 6 minutes with 8 tickets given more time for the money.

Answer:

24 biros

Step-by-step explanation:

12.50 naira = 1 biro

300 ÷ 12.50 = 24 biros

Answer:

24

It's a ratio problem

Let B is Biro and N naira

B   :      N

1    :     12.5

x    :      300

then x = 300 * (multply) 1 /12.5 = 24
