5 (4x2) + 6 - (2x2) - 1
5 + 6 = 11, 4 x 2 = 8
2 x 2 = 4, 11 + 6 = 17
17 - 1 = 16

Answer:

x = 21

Step-by-step explanation:

Diagonal angles are equal to eachother, so 143 = 6x +17

143 = 6x + 17

Subtract 17 from both sides

126 = 6x

Divide by 6

21 = x

To check put x as 21

143 = 6(21) + 17

Mutiply 6 by 21

143 = 126 + 17

add 17

143 = 143

A travel agent calculates the cost of a trip to Paris using this formula c=p (t+30) c is the total cost in pounds p is the numbe

Triss [41]

C=p(t+30)

Let’s substitute in our values...

c=2(245+30)

Get the sum of what we have in parentheses...

c=2(275)

And finally

c=550

X²-10+3x=0 la ecuación es completa o incompleta?

hjlf

Answer:

Yes, the equation is complete.

Step-by-step explanation:

The given quadratic equation, x² + 3x - 10 = 0 is expressed in standard form, <em>a</em>x² + <em>b</em>x + <em>c</em> = 0.

Where: a = 1, b = 3, and c = -10.

Using the quadratic formula:

$x = \frac{-b (+/-) \sqrt{b^{2} - 4ac} }{2a}$

We can solve for its solution by plugging in the values for <em>a, b</em>, and <em>c</em>.

$x = \frac{-b (+/-) \sqrt{b^{2} - 4ac} }{2a}$

$x = \frac{-3 (+/-) \sqrt{(3)^{2} - 4(1)(-10)} }{2(1)}$

$x = \frac{-3 (+/-) \sqrt{9 + 40} }{2}$

$x = \frac{-3 (+/-) \sqrt{49} }{2}$

$x = \frac{-3 + 7 }{2}$ , $x = \frac{-3 - 7 }{2}$

$x = \frac{4}{2} = 2$ , $x = \frac{-10 }{2} = - 5$

Therefore, the solutions of the quadratic equation, x² + 3x - 10 = 0 is:

x = 2, and x = -5
