The given trinomial can be factored using factorization as

x²-x-12
=x²-4x+3x-12
=x(x-4)+3(x-4)
=(x-4)(x+3)

Thus x-4 and x+3 are the factors of the given trinomial. From these we can see x+3 is listed in option A

So the answer to this question is Option A

Janet is 5 years older than her sister.the sum of their ages is 51.how old is her sister
Mazyrski [523]
Let us assume that the age of Janet's sister is = x
Then the age of Janet = x + 5
Now we also know that their combined age is equal to 51 years. Then we can write the equation as
x + (x + 5) = 51
2x + 5 = 51
2x = 51 -5
2x = 46
x = 46/2
   = 23
So the age of Janet = x + 5
                                = 23 + 5
                                 = 28 years
So the age of Janet's sister is 23 and Janet's age is 28

Understanding the Pythagorean Theorem – Finding an Unknown Hypotenuse (find the distance of the mechanical webbing needed by Spi
barxatty [35]

Answer:

100√65 yds

Step-by-step explanation:

The Pythagorean Theorem is a^2+b^2=c^2. In this case a=700, b=400, and c is the unknown.

  • 700^2+400^2=c^2
  • 490000+160000=c^2
  • 650000=c^2
  • c=√650000

√650000=√(100^2•65)=100√65

AleksAgata [21]

Answer:

B. 19 inches and 60 inches.

Step-by-step explanation:

Required

Select matching pairs

Represent diameter with D and Circumference with C

C is calculated as:

Where

A. D = 5m; C = 22m

Using:

15.71 does not approximates to 22m.

Hence, the pair do not match

B. D = 19 in; C = 60 in

Using:

59.698 approximates to 60.

Hence, the pair match

C. D = 33 cm; D = 80 cm.

Using:

103.686 does not approximates to 22m.

Hence, the pair do not match

From the analysis above, only option B matches the diameter with the circumference
