Select the property of equality used to arrive at the conclusion. if x = 2, then x + 8 = 10 the multiplication property of equality the division property of equality the addition property of equality the subtraction property of equality

 The subtraction property of equality

Step-by-step explanation:

Hi, to answer this question qe have to analyze the equation given:

x +8 = 10

According to the subtraction property of equality, we have to subtract 8 from each side of the equation, because they are equivalent.

x+8 -8 =10 -8

x= 2

So, applying this property we arrive at the conclusion that x=2

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
