Answer:
12
Step-by-step explanation:
4 x 3 is 12
See attachment for one such shell. The volume is given by the sum of infinitely many thin shells like this, each with radius
and height determined by the vertical distance between the upper blue curve and the lower orange curve for any given
, i.e.
.
The volume is then
Answer:
x>−6
Step-by-step explanation:
-6x<36
Multiply both sides by -1. ( reverse the inequality )
(-6x) (-1) > 36 (-1)
Simplify
6x > -36
Divide both sides by 6
6x divided by 6 -36 divided by 6
Simplify
x> -6
Hope this helped
15. -(-7y + 12) = 7y - 12
16. 1/a = 16/18
cross multiply
16a = 18
a = 18/16 = 9/8
17. 8x - 12 = 4x + 24
8x - 4x = 24 + 12
4x = 36
x = 36/4
x = 9
18. -6b > 42 4b > -4
b < 42/-6 b > -4/4
b < - 7 b > -1
so b < -7 and b > -1
19. 6 more then the product of 8 and n
6 + 8n
20. 45 = 3b + 69
45 - 69 = 3b
-24 = 3b
-24/3 = b
-8 = b
