9+m/3=2help me please
Verizon [17]

Answer:

m = -21

Step-by-step explanation:

9+m/3=2

1. Subtract 9 from both sides

9 - 9 + m/3 = 2 - 9

m/3 = -7

2. Multiply both sides by 3

3 (m/3) = -7 (3)

m = -21

If x^2-x-6 and x^2+3x-18 hacpve a common factor (x-a) then find the value of a.​
DedPeter [7]

Answer:

a = 3

Step-by-step explanation:

Factor both expressions

x² - x - 6

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)

The factors are - 3 and + 2 , since

- 3 × 2 = - 6 and - 3 + 2 = - 1 , thus

x² - x - 6 = (x - 3)(x + 2)

-----------------------------------

x² + 3x - 18

consider factors of constant term (- 18) which sum to give the coefficient of the x- term (+ 3)

The factors are + 6 and - 3 , since

6 × - 3 = - 18 and 6 - 3 = + 3 , thus

x² + 3x - 18 = (x + 6)(x - 3)

Both expressions have a common factor of (x - 3)

Compare with (x - a ), then a = 3

4th grade math. Help?!
viva [34]

Answer: Well... does it give you the approximate length or actual length of the butterfly? If so, you would take that length and multiply it by 5. That would give you the length of the 5 butterfly lined up together.

If it does not give you the approximate length or actual length, look up the length on google.  (Google Answer- Size: 2.5" - 4.0" range.)

Take that and multiply it by five to get the length of the 5 butterflies.
