Hi! Let me help you! :)

  • Remember, factoring looks like so:
  • ab+ac=a(b+c)
  • In this case, a is the common term, so we factor it out.
  • Now, let's check our polynomial and see if we can spot the common term.
  • All terms are divisible by 4, so 4 is the common term.
  • 4x²-4x-8
  • x²-x-2

<u>Answer:</u>

x²-x-2

Hope you find it helpful.

A researcher studied the relationship between the number of times a certain speciesof cricket will chirp in one minute and the t
cricket20 [7]

Answer:

C. Actual temperature of 57.1°F when the cricket has chirped 116 times

Explanation:

The x-axis represents the number of chirps per minute.

The values on the y-axis represent the temperature (in °F).

Given the point (116, 57.1)

• The number of chirps per minute = 116

,

• Temperature = 57.1°F

Thus, the point (116, 57.1) represent an actual temperature of 57.1°F when the cricket has chirped 116 times.

So:

-5/6 divided by -1/3=

-5/6* -3

Which is congruent to 5/6 divided by 1/3

What is the distance between (−10, −2) and (−4, −2) ? −14 units −6 units 6 units 14 units
Lesechka [4]

Answer:

6 units

Step-by-step explanation:

to calculate the distance d between the points use the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁)²

with (x₁, y₁ ) = (- 10, - 2) and (x₂, y₂ ) = (- 4, - 2)

d = \sqrt{(-4+10)^2+(-2+2)^2} = \sqrt{6^2+0^2} = \sqrt{36} = 6

What theorem or postulate can be used to justify that the two triangles are congruent? Write a congruence statement.
Alinara [238K]

B

ASA is short for angle side angle, which you can see from angle B and angle D being congruent (all right angles are congruent), the congruent marks on line BE and line ED, and the vertical angles AEB and DEC.

D is not the answer because B and D are not in the same 'place' when naming. Silly as it is, it counts.

Hope this helps!
