Use this 3 following steps:
1)At first, we should find the roots :
3x+8=0 => x=-8/3
x-4=0 => x=4
2)Using a chart for the limits:

3)choose your solution:
[-8/3,-4)==> Sentence 3 is correct
Answer:
0.256 * 10⁻⁵
Step-by-step explanation:
Probability of picking any answer out of 5 given options = 1/5
Total probability for 8 questions = (1/5)⁸ = 0.00000256
= 0.256 * 10⁻⁵
Perimeter = 0.75 * 3 = 2.25 <span>inches</span>
The answer is 13z>-3z-3 because if you distribute the -3 you get -3z-3 and if u subtract the -z from the 14z you get 13z
The angle A is equal to B because they are opposite angles by the vertex.
So...
5x - 15 = 2x + 21
For solve it, we are going to do the same operations in both sides of the equal sign. We need put all the X in a side of the equal sign and all the free numbers in the other side.
5x - 15 = 2x + 21
We are going to add 15
5x - 15 + 15 = 2x + 21 + 15
5x = 2x + 36
We are going to substract 2x
5x - 2x = 2x + 36 - 2x
3x = 36
We are going to divide by 3
3x/3 = 36/3
x = 12
<h2>X = 12</h2>
and
<h2>B = A</h2>
