Answer:
D
Step-by-step explanation:
Factor out 3 x from the expression
3x X (1+3y^3+4x^4)
(4x+28)+(x+19)+(3x+13)=180
8x+60=180( combine like terms)
8x+60-60= 180-60
8x=120
8/8x=120/8
x=15
The missing angles are 88°, 34° and 58°
Answer:
How do you describe the solution set to a system of linear inequalities?
Step-by-step explanation:
The solutions of a system of linear inequalities are all the ordered pairs that make all the inequalities in the system true.
Answer:
D
Step-by-step explanation:
Given
- 12 ≤ 2x - 4 < 10 ( add 4 to all 3 intervals )
- 8 ≤ 2x < 14 ( divide all 3 intervals by 2 )
- 4 ≤ x < 7
