Answer:
The solution of the given set in interval form is ![$(-\infty,-4] \cup[12, \infty)$](https://tex.z-dn.net/?f=%24%28-%5Cinfty%2C-4%5D%20%5Ccup%5B12%2C%20%5Cinfty%29%24)
.
Step-by-step explanation:
It is given in the question an inequality as 
.
It is required to determine the solution of the inequality.
To determine the solution of the inequality, solve the inequality 
and, 
Step 1 of 2
Solve the inequality
Solve the inequality .
Step 2 of 2
The common solution from the above two solutions is x less than -4 and 
.
The solution set in terms of interval is .
Answer:
ΔNAS≅ΔSEN by SSA axiom of congruency.
Step-by-step explanation:
Consider ΔNAS and ΔSEN,
NS=SN(Common ie . Both are the same side)
SA=NE( Given in the question that SA≅ NE)
∠SNA=∠NSE( Due to corresponding angle property where SE ║ NA)
Therefore, ΔNAS ≅ΔSEN by SSA axiom of congruency.
∴ NA≅SA by congruent parts of congruent Δ. Hence, proved.
Answer:
E. -8, -29
Step-by-step explanation:
a-b=21
5a -2b =18
Take the first equation and solve for a by adding b to each side
a-b=21
a-b+b=21+b
a = 21+b
Now substitute a=21+b into the second equation
5a -2b =18
5(21+b) -2b =18
Distribute the 5
105 +5b-2b =18
Combine like terms
105 +3b =18
Subtract 105 from each side
105-105 +3b = 18-105
3b = -87
Divide each side by 3
3b/3 =-87/3
b = -29
if b = -29, we can substitute it into a =21+b
a = 21-29
a = -8
