Answer:

7

Step-by-step explanation:

Comparing the two similar triangles

JK/MN = JL/MP

25/30 = 20/(4X - 4)

CROSS MULTIPLY

25(4X - 4) = 30 × 20

100X - 100 = 600

COLLECTING LIKE TERMS

100X = 600 + 100

100X = 700

DIVIDING THROUGH BY 100

X = 700/100

X = 7

What are the solutions to the equation x2−12x+100=0?
marysya [2.9K]

Answer:

x=6+8i

x=6-8i

Step-by-step explanation:

x^2-12x+100=0

solve by quadratic formula.

\frac{-b+-\sqrt{b^2-4(a*c)} }{2*a}

\frac{12+\sqrt{(-12)^2-4*(1*100)} }{2*1}

\frac{12-\sqrt{(-12)^2-4*(1*100)} }{2*1}

which is

x=\frac{12+16i}{2}

x=\frac{12-16i}{2}

Simplify.

x=6+8i

x=6-8i

Solved.


Hope this helps.

(-4,2) (5,0) midpoint
Archy [21]

Answer:

M = (0.5, 1)

Step-by-step explanation:

The midpoint can be found using the formula: x, y = (\frac{x_2+x_1}{2}, \frac{y_2 + y_1}{2})

So plugging in the values we get: M = (\frac{-4+5}{2}, \frac{2+0}{2})\\M = (\frac{1}{2}, \frac{2}{2})\\M = (0.5, 1)
