Answer:

13. x=0, x= -4

14. NO EXCLUDED VALUE

Step-by-step explanation:

13. set the denominator to equal to 0 = x^2 + 4x = 0

factor the expression x × (x + 4) = 0

separate into possible cases = x = 0 and x = -4

state the excluded value = x = 0 and x = -4

14. set the denominators equal to 9 = x^2 +81 = 0

the statement is false for any value if x = x € ℝ

Olin [163]

Answer:

-2x^2 +16x -8

Step-by-step explanation:

Oh s-

Like terms i guess Same variable you can substract. Remember you only substract from 1 number not from all.

-2x^2 stays the same as there is no like term

9x - (-7x)

-2 - (6)

-2x^2 + 9x+ 7x -2-6

-2x^2 +16x -8

I really don’t get this math how am i supposed to figure out which side is which?
Arada [10]

Answer:

u can use "a squared + b squared = c squared"

in this case the two legs are 10 and 24 because they are near the right angle. the hypotenuse is always across from the right angle, so it's the long side that connects the two legs. Now you can plug in 10 and 24 for the pythagorean theorem and solve for the hypotenuse. that would be 10 squared plus 24 squared equal to c squared.

Elliot's employer pays time-and-a-half for all hours worked over 40 hours per week. Elliot's regular hourly rate is $9 per hour.
musickatia [10]
E=9h+1.5(9)(h-40)

e=9h+13.5(h-40), since h=49

e=9(40)+13.5(9)

e=9(40+13.5)

e=9(53.5)

e=$481.50
