Answer:

<em>the answer is c</em>

( 2 x + 3 y ) ( 2 x − 3 y ) is the factored form of the expression

Step-by-step explanation:

4 x 2 − 9 y 2 can be also written as ( 2 x ) 2 − ( 3 y ) 2
Now, as per identity: a 2 − b 2 = ( a + b ) ( a − b )
So , in case of our expression a = 2 x , b = 3 y ( 2 x ) 2 − ( 3 y ) 2 = ( 2 x + 3 y ) ( 2 x − 3 y )

xenn [34]

The straight line is perpendicular to y = -3x + 4.

Therefore, the gradient of the straight line must be 3.

The equation of the straight line is y = 3x + 2.

Answer:

1) x= -36.

2) x = 0.

Step-by-step explanation:

1) Taking the 3rd power to both sides and using the following exponent law:

$\left(a^b\right)^c = a^{bc}$

we get:

$\left(\left(m^{x}\right)^{\frac{1}{3}}\right)^3 = \left(m^{-12}\right)^3 \\ m^x = m^{-36}$

So this tells us that x = -36.

2) We can distribute the power inside every term. So the left side becomes:

$\left(3x^3y^x\right)^3 = 3^3\left(x^3)^3y^{3x} = 27x^9y^{3x}$

Now, the trick here is to remember that $y^0 = 1$ , so replacing 1 with $y^0$ , which then gives us:

$27x^9y^{3x} = 27x^9y^{0}$ , telling us that 3x = 0 and thus, x = 0.

Given:

iragen [17]

AC = BC gives you one pair of congruent sides.
<3 = <4 gives you a pair of congruent angles.

You already have SA.
Maybe you can add another pair of congruent angles to use ASA,
or maybe you can add another pair of congruent sides to use SAS.

Now we look at the drawing and see what we can add to what we have.
We don't know anything about angles A and B to use ASA.

We see side CM which is a side of both triangles.
A segment is congruent to itself. Since side CM is a side of both triangles, that is the other pair of congruent sides.

We can use SAS.

Answer: SAS
