Answer:

Step-by-step explanation:

First we need to find the score of the incorrect answers and the questions that were not answered.

Score for the incorrect answers = 4*(-2) = -8

Score for the questions not answered = 6*(-1) = -6

Score for the questions answered correctly = 106 - [ (-8) + (-6) ]

                                                                       = 106 -[-14]

                                                                        = 106 + 14

                                                                        = 120

Number of questions answered correctly = total score for questions that were answered correctly ÷ score of 1 correct answer

= 120 ÷ 4

= 30

30 questions were answered correctly.

Divide a 5 1/4 inch line into three parts whose ratios are 1:2:3.
stich3 [128]
1:2:3...total is 6

1/6 of 5 1/4 = 1/6 * 21/4 = 21/24 = 7/8
2/6 of 5 1/4 = 2/6 * 21/4 = 42/24 = 1 3/4
3/6 of 5 1/4 = 3/6 * 21/4 = 63/24 =  2 5/8

7/8, 1 3/4, 2 5/8...total = 5 1/4 inches

IM NOT UNDERSTAND THIS EQUATION CAN SOMEBODY HELP ME
aleksley [76]

Answer:

  • x = 0, mult: 3
  • x = -4, mult: 2
  • x = -5, mult: 2

Step-by-step explanation:

When a polynomial is shown in factored form, its zeros are the values of x that make the factors zero.

  The factor x is zero when x=0.

  The factor (x+4) is zero when x=-4.

  The factor (x+5) is zero when x=-5.

__

The multiplicity of a zero is the number of times a given factor is a factor of the polynomial. It is the exponent of the factor.

 x = 0 has multiplicity 3.

  x = -4 has multiplicity 2.

  x = -5 has multiplicity 2.

<span>Solution:

</span></span><span>-|-12|-|-25-2| 

-12-27

NOTE: The negative outside the absolute value would be negative, so meaning that after you solve the inside absolute value equation, and you have negative outside, the number would be negative.
