-4 | x + 5 | = -16...divide both sides by -4, eliminating it on the left side
| x + 5 | = -16/-4
| x + 5 | = 4
x + 5 = 4 -(x + 5) = 4
x = 4 - 5 -x - 5 = 4
x = -1 -x = 4 + 5
-x = 9
x = -9
solutions : x = -1 , x = -9
Answer:
C
Step-by-step explanation:
Answer:
Step-by-step explanation:
x+2x=90
x+2x=90, 90divided by 3 is 30, 30 is x, 2(30) is 60.
2x+5+3x+10=90, 90-15=75, 75 divided by 5=15, x=15
2(15)+5=35
3(15)+10=55
Answer:
1. X=35 degrees obtuse
2 x=25 degrees right
Step-by-step explanation:
Background info:
The measures of the angels of every triangle is 180 degrees
So x equals 180 minus the other angles combined
1. X=180-(40+105)
X=180-145
X=35 degrees
2.
x=180-(90+65)
x=180-155
x=25 degrees
