Do you know that multiplicity means the number of times any factor appears in the factored result? Just checking. For example The graph of y = x^2 - 2x + 1 has a multiplicity of 2. they are y = (x - 1) * ( x - 1)

y = x^2 - 3x - 4 has 2 factors.
y = (x - 4)(x + 1) each of the factors has a multiplicity of 1. 

So the answer to your question is there are 5 real zeros and 2 complex zeros.

For the figures shown, FHJL ~ NPRS. The scale factor applied to FHJL to create NPRS is 4 to 3.
GrogVix [38]

Remark

For every 3 units for NP will be 4 units. You can set up a proportion.

\dfrac{3}{4} = \dfrac{45}{NP}\text{Cross Multiply}

3*NP = 4*45

3*NP = 180 Divide by 3

NP = 180/3

NP = 60

Help with my math i will mark brainliest
Svetlanka [38]

Answer:

D

Step-by-step explanation:

step 1: find the slope

slope is 2/-4 = -1/2

then plug in the value for x to y, you get +1 for the y intercept

then it becomes y=-1/2x + 1

I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!

Answer:

  1. 125 in²
  2. 676 km²
  3. 20 square units

Step-by-step explanation:

The Pythagorean theorem tells you the square on the hypotenuse is equal to the sum of the squares on the other two sides. (This is the version you use for problem 2.)

This also means the square on one side is the difference between the square on the hypotenuse and the square on the other side. (Use this version for problems 1 and 3.)

1. ? = 200 in² -75 in² = 125 in²

2. ? = 576 km² + 100 km² = 676 km²

3. ? = 36 square units - 16 square units = 20 square units
