Mathematics
1 answer:
ohaa [14]3 years ago
4 0

The given compound inequality is

2(x+3)>6 \ or \ 2x+3\leq  -7

First we solve the first inequality,

2(x+3)>6
\\
x+3 >3
\\
x>0

Now we solve the second inequality

2x+3\leq -7
\\
2x \leq  -7-3
\\
2x\leq  -10
\\
x\leq  -5

So we have

x > 0 \ or  \ x\leq  -5

So the required solution is

( - \infty,-5] \ or \ (0, \infty)

Correct option is A .

seeing in triangle ABD angle A equals 67 you would multiply that by 2 and then subtract it from 180 to get 46, and then triangle DBC all the angles would equal 60. so then add 46 to 60 to get 106 the measure of <ABC
