Answer:
Step-by-step explanation:
multiply by 
on each side
add 1 on both sides 
make it equal 0
Factor
answer is 3 and -1
X <= -2 and 2x >= 6 is the smae as
x<= -2 Nd x >+ 3
Now x cannot satisfy both inequalities so the first one has no solution
Answer:
4.0731 cm
Step-by-step explanation:
Use pythagorean Theorem which is a^2 + b^2 = c^2 where a and b are the sides of the triangle and c is the hypotenuse, in other words the longest side.
Since x is in line with the center of the circle and is perpendicular with line that measures 15.6 cm we know that one side of the triangle is half of 15.6 or 7.8.
So then we input our known values into the formula and solve for the missing one. The formula looks like this
7.8^2 + b^2 = 8.8^2
solve for b and you get about 4.07431
your very welcome
