\huge\text{Hey there!}

\huge\textsf{28 - 4a = 3a - 14 + 2a}

\huge\boxed{\rightarrow}\huge\textsf{ 28 - 4a = 5a - 14}

\huge\boxed{\rightarrow}}\huge\textsf{ -4a + 28 = 5a - 14}

\huge\text{SUBTRACT \underline{\underline{5a}} to  BOTH SIDES}

\huge\textsf{-4a + 28 - 5a = 5a - 14 - 5a}

\huge\boxed{\rightarrow}\huge\textsf{ -9a + 28 = -14}

\huge\text{SUBTRACT \underline{\underline{28}} to BOTH SIDES}

\huge\textsf{-9a + 28 - 28 = -14 - 28}

\huge\boxed{\rightarrow}}\huge\textsf{ -9a = -42}

\huge\text{DIVIDE \underline{\underline{-9}} to BOTH SIDES}

\huge\boxed{\mathsf{\dfrac{-9a}{-9}=\dfrac{-42}{-9}}}

\huge\boxed{\rightarrow}\huge\boxed{\star\ \mathsf{\ a = \dfrac{14}{3}}\ \star}

\huge\boxed{\mathsf{Therefore, your \ answer\  is: a = \bf \dfrac{14}{3} }}\huge\checkmark

This diagram is a straightedge and compass construction. A is the center of one circle,
zepelin [54]

ABC is a equilateral triangle .

Proof :-

Let's assume both circles as C1 and C2 [ as shown in the figure ]

  • AB is the radius of circle C1
  • AB is the radius of Circle C2

AC is the radius of circle C1.

BC is the radius of circle C2 .

AB and AC both are radius of circle C1 so both are equal ie AB = AC .

AB and BC both are radius of circle C 2 so both are equal ie AB = BC .

Hence we conclude that .

AB = BC = AC.

So the triangle is equilateral triangle.

How would you factor a quadratic expression like 9x^2-4
Ganezh [65]

Hello, we need to see it as a difference of two squares as we know that for all a and b real numbers

a^2-b^2=(a-b)(a+b)

So, here

9x^2-4=(3x)^2-2^2=(3x-2)(3x+2)

Voila !

Thank you

What is the domain and derivative of f(x)=ln(2xsqrt(2+x))?
wolverine [178]
For domain 2x sqrt(2+x)>0
x>0,2+x>0,x>-2 combining 
we get x>2
f'(x)=[1/{2x sqrt(2+x)}][{2x/(2 sqrt(2+x))}+2 sqrt(2+x)]
