Step-by-step explanation:

(x+5)^2 = 2( 5x-3)

x^2+25=10x-6

x^2-10x+25+6= 0

x^2-10x+31=0

a=1, b

Answer:

\boxed{-124}

Step-by-step explanation:

(x+5)^2 = 2( 5x-3)\\x^2+10x+25=10x-6\\x^2+0x+31=0

ax^2 +bx +c=0

Formula for the discriminant:

D=b^2-4ac

b=0\\a=1\\c=31

Plug in the values.

D=0^2-4(1)(31)

D=-124

PLEASE HELP 50 COINS!!!!

Answer:

Therefore,

AB=16.25\ units

The Measurement of AB is 16.25 units.

Step-by-step explanation:

In Right Angle Triangle ABC

m∠C=90°

AC = 10.01    .....(Adjacent Side to angle A)

m∠A=52°

cos 52 ≈ 0.616

To Find:

AB = ? (Hypotenuse)

Solution:

In Right Angle Triangle ABC, Cosine Identity,

\cos A= \dfrac{\textrm{side adjacent to angle A}}{Hypotenuse}\\

Substituting the values we get

\cos 52= \dfrac{AC}{AB}=\dfrac{10.01}{AB}

But cos 52 ≈ 0.616 ....Given

AB=\dfrac{10.01}{0.616}=16.25\ units

Therefore,

AB=16.25\ units

The Measurement of AB is 16.25 units.

Answer:

La respuesta correcta es la opción d) 5 a 1.

Step-by-step explanation:

Para calcular la relación entre los ingresos de Mary en 2019 (I_{2019}) con respecto a sus ingresos en 2018 (I_{2018}), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:

I_{2019} = 20\% \: I_{2018}      

I_{2019} = \frac{20}{100}I_{2018}      

\frac{100}{20}I_{2019} = I_{2018}        

5I_{2019} = I_{2018}                  

Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.

Espero que te sea de utilidad!
