Find EF given E(-7, -2) and F(11, 3). Round your answer to the nearest thousandth (3 decimal places).

zavuch27 [327]

Answer:

18.682

Step-by-step explanation:

Given that :

E = (-7, - 2) ; x1 = - 7 ; y1 = - 2

F = (11, 3) ; x2 = 11 ; y2 = 3

EF = √((x2 - x1)² + (y2 - y1)²)

EF = √((11 - -7)² + (3 - -2)²)

EF = √((11 + 7)² + (3 + 2)²)

EF = √(18² + 5²)

EF = √324 + 25

EF = √349

EF = 18.6815

EF = 18.682 units (3 decimal places )

Which of these correctly rearranges the terms in this polynomial so like terms are next to each other?3 – 6x + 4x2 + 3x – 6x2 –

fomenos

Answer:

The rearrangement of the terms is $4x^2-6x^2-6x+3x+3-4$ .

Step-by-step explanation:

The given expression is

$3-6x+4x^2+3x-6x^2-4$

Two terms are called like terms if they have same variables having same degree.

In the given expression 3 and -4, -6x and 3x, 4x² and -6x² are like terms.

Arrange the given terms according to their degree and arrange in this way so like terms are next to each other.

$4x^2-6x^2-6x+3x+3-4$

Therefore the rearrangement of the terms is $4x^2-6x^2-6x+3x+3-4$ .
