Answer:
3x+13
Step-by-step explanation:
-(x-2) =-x+2
3x+6+7
3x+13
Okay, so the open sentence is basically telling you that -2 is less than or equal to n+4, and n+4 is less than or equal to seven. Do you know where to go from there?
The value of x that fills the coordinate are 7 or -5
<h3>Distance between two points</h3>
The formula for calculating the distance between two points is expressed as:
D = √(x2-x1)² +(y2-y1)²
Substitute the given coordinates
10 = √(15-7)² +(1-x)²
100 = 8² +(1-x)²
(1-x)² = 100 - 64
(1-x)² = 36
1- x = -6
x = 7 or -5
Hence the value of x that fills the coordinate are 7 or -5

Complete question
<em>If the distance between two points (x, 7) and (1, 15) is 10, find the value of x.</em>
Answer:
Step-by-step explanation:
Question (1)
x² + 10x + 12
= x² + 2(5x) + 5² - 5² + 12
= [x² + 2(5x) + 5²] - 5² + 12
= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]
= (x + 5)² - 13
Question (2)
y² - 6y - 15
= y² - 2(3y) - 15
= y² - 2(3y) + 3² - 3² - 15
= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]
= (y - 3)² - 3²- 15
= (y - 3)² - 9 - 15
= (y - 3)² - 24
