Answer:
x>
and x ≤
.
Step-by-step explanation:
Given : −9x+2>18 AND 13x+15≤−4.
To find : Solve.
Solution : We have given −9x+2>18 AND 13x+15≤−4.
For −9x + 2 > 18 .
On subtracting both sides by 2
- 9x > 18-2
- 9x > 16.
On dividing both sides by -9.
x>
.
For 13x + 15 ≤ −4.
On subtracting both sides by 15.
13 x ≤ -4 - 15.
13 x ≤ -19.
On dividing both sides by 13.
x ≤
.
Therefore, x>
and x≤
.

(2)
SA=(12*4)+(16*4)+(20*4)+(

)
SA= 28+64+80+(6*16*2)
SA=28+64+80+(96*2)
SA=28+64+80+192
SA=364
