Answer 1

Answer:

Step-by-step explanation:

You would do 2[3]+3 because you plug in the three for the x and it gives you 9 if you use a calculator be sure to use [ ] where needed.

Answer 2

Answer:

Answer:

Step-by-step explanation:

Plug in 3 where x is.

2(x) + 3

At present Asha's age (in years) is two more than the square of her daughter Nisha's age (in years). When Nisha grows to her mother's present age, Asha's age would be one year less than 10 times the present age of Nisha. Find the present age of Asha and Nisha

Answers

Answer:

Asha's present age is 27 years and Nisha's present age is 5 years.

Step-by-step explanation:

Let the present age of Nisha be $x$ years.

As per question, Asha's present age is 2 more than the square of Nisha's age.

$\therefore$ Asha's present age = $x^2+2$

Now, Nisha will reach her mother's age after $x^2+2-x$ years.

Therefore, age of Asha after $x^2+2-x$ years will be = $x^2+2+x^2+2-x=2x^2-x+4$

Now, as per question,

$2x^2-x+4=10x-1\n2x^2-x-10x+4+1=0\n2x^2-11x+5=0\n2x^2-x-10x+5=0\nx(2x-1)-5(2x-1)=0\n(2x-1)(x-5)=0\nx=(1)/(2)\ or\ x=5$

As age can't be in fraction, we consider the present age of Nisha as 5 years. So, Asha's present age is $x^2+2=5^2+2=25+2=27$ years.

Therefore, Asha's present age is 27 years and Nisha's present age is 5 years.

What is the value of x? º A triangle with base on an extended line. Two angle measures are given. Top interior angle is twenty-eight degrees. Lower left exterior angle is seventy-one degrees. Lower right interior angle is labeled x degrees.

Answers

All interior angles of a triangle must have a sum of 180°.
Interior angle of a triangle and its corresponding exterior angle must have a sum of 180° when its line is extended.

Top interior angle is 28°
Lower left exterior angle is 71°
Lower right interior angle is x°

Get the left interior angle.
Exterior angle + Interior angle = 180°
71° + Interior angle = 180°
Interior Angle = 180° - 71°
Interior Angle = 109°

Top Interior angle + Left Interior Angle + Right Interior angle = 180°
28° + 109° + x° = 180°
x = 180° - 28° - 109°
x = 180° - 137°
x = 43°

The lower right interior angle is 43°

N^2+7n+15=5
show work please

Answers

n^2+7n+15=5
n^2 + 7n + 10 = 0
(n + 5)(n + 2) = 0
n + 5 = 0
n = -5
n + 2 = 0
n = -2

Answer: n = -5 and -2

$n^2+7n+15=5$

$n^2+7n=-10$

$n^2+7n+((7)/(2))^2=-10+((7)/(2))^2$

$n^2+7n+(49)/(4)=-10+(49)/(4)$

$(n+(7)/(2))^2=(9)/(4)$

$n+(7)/(2)=\sqrt{(9)/(4)}$

$n=-(7)/(2)+\sqrt{(9)/(4)}$

$n=-2$
$n=-5$
