I hope this helps you
x^2+2x+8=0
x^2+2x+1+7=0
(x+1)^2= -7
(x+1)^2= i^2.7
x+1= i.square root of 7
x=-1+ i.square root of 7
The slope of any line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
The given points are (-14,-10) and (7,5), therefore:
y2 = 5
y1 = -10
x2 = 7
x1 = -14
Substitute with these values to get the value of the slope as follows:
slope = (5--10) / (7--14) = 5/7
Answer: Each peice of wood is equal to 0.625
Step-by-step explanation:
15/2 = 7.5
7.5/12 = 0.625
