Answer:

The value of x is 14.

Step-by-step explanation:

We know that:

ΔABC ≅ ΔEFG
21 x 2/3 = x

Work:

21 x 2/3 = x
=> 7 x 3 x 2/3 = x
=> 7 x 2 = x
=> 14 = x

Hence, the value of x is 14.

Hoped this helped.

Find the m please it’s due today . (-11,5) & (2,-4)

d1i1m1o1n [39]

Answer:

m = $\frac{-9}{13}$

Step-by-step explanation:

I'm assuming by m, you mean the slope.

You have two points. (-11, 5) and (2, -4)

m = change in y-value ÷ change in x-value

1) Substitute in the points.

m = $\frac{(-4)- 5}{2 - (-11)}$

2) Solve.

-4 - 5 = -9

2 - (-11) = 13

So, the slope would equal $\frac{-9}{13}$ .

What are the zeros of 3x²(x+π)³(x-4)²

Aneli [31]

Hi again!

The zeros are the values of x. This is where the graph intersects the x - axis. In order to find the zeros, replace y with 0 and solve for x.

The answer is x = 0, -π, 4

I am not sure what grade are you or the level, but for me, they sometimes asked me to find their multiplicities as well

The multiplicity of a root is the number of times the root appears.

So, the answer are
x = 0 and the multiplicity of 2
x = -π and the multiplicity of 3
x = 4 and the multiplicity of 2

Good luck with your studies!
