Answer:
-3 < x ≤ -1
Step-by-step explanation:
-8 < 5x + 7 ≤ 2
First, subtract 7 from all sides of the inequality:
-8 - 7 < 5x + 7 - 7 ≤ 2 - 7
-15 < 5x < -5
Divide all sides by 5 to isolate x:
-15 ÷ 5 < 5x ÷ 5 ≤ -5 ÷4
-3 < x ≤ -1
Hope this helps!
Answer:
-4x=y
Step-by-step explanation:
1) y=-x/4
2) x=-y/4
3) 4x=-y
4) -4x=y
Ac - ab = 2
Factor out a
a(c-b) = 2
Then divide the expression by c-b to solve for a.
Do this on both sides.
a(c-b)/(c-b) = 2/(c-b)
a = 2/c-b
The solution is a = 2/c-b.

Step-by-step explanation:
i know
The triangle area is 7*2/2 = 7.
The volume is the triangle area times the side length, so 7*18 = 126 cm3
