Answer:
8.5
Step-by-step explanation:
Ok the answer is -5 less than 9 which is true lol
Anyways here’s how I got the answer
-5+7+2x-13 less than 9
Combine like terms in this case it’s -5 and 2, and the other is 7 and -13
-5+2= -3
7-13= -6
Ok now that that’s done here’s the next step
-3x-6 less than 9 solve it
-3x-6 < 9
+6< +6
-3x < 15
Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5
And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)

Answer:
13,600 
Step-by-step explanation:
(h = 7, l = 6, w = 2) 10
70, 60, 20
2(h × w) + 2(h × l) + 2(w × l)
= 2(70 × 20) + 2(70 × 60) + 2(20 × 60)
= 2(1400) + 2(4200) + 2(1200)
= 2800 + 8400 + 2400
= 13,600
