Answer:

x=4 and x=3

Step-by-step explanation:

The first step to find all factors of 12

1,2,3,4,6,12

and their negative form

-1,-2,-3,-4,-6,-12

we must add two of these numbers to get -7

and the two numbers that add up to -7 are -3 and -4

we can simply plot them into the polynomial (x-3)(x-4)

since x-3=0

we add three to both sides to get x=3

and since x-4=0

add four to both sides

we get x=4

and now check out work which

we can use First out in last (foil) method

(x-3)(x-4)

first

x^2

out

-4x

in

-3x

last

12

now we simplify to get x^2-7x+12

so it x=4 x=3 works

How do i answer this?<br>3(m-2)=2(3m+3)
krek1111 [17]
3 (m - 2) = 2 (3m + 3)   Use the Distributive Property on both sides
   3m - 6 = 6m + 6        Subtract 6m from both sides
  -3m - 6 = 6                 Add 6 to both sides
        -3m = 12               Divide both sides by -3
           m = -4

In the data set below, which of these points is most likely and outlier?
shusha [124]
<h2>Answer:</h2>

Option: D is the correct answer.

                 D.  (2,54)

<h2>Step-by-step explanation:</h2>

We know that an outlier of a data set is the value that stands out of the rest of the data point i.e. either it is a too high value or a too low value as compared to other data points.

Here  we are given a set of data points as:

         (2,54)

          (4,7)

         (6, 9)

         (8,12)

         (10,15)

Hence, we see that the output values i.e. 7 in (4,7) ; 9 in (6,9) ; 12 in (8,12) and 15 in (10,15) are closely related.

Hence, the data point that is an outlier is:

                  (2,54)

(As 54 is a much high value as compared to other)

If four of the exterior angles of a convex pentagon measure
MakcuM [25]

Answer:

120 degrees.

Step-by-step explanation:

The 5 exterior angles sum to 360 degrees.

So the 5th exterior angle = 360 - 4(60)

= 360 - 240

= 120 degrees.
