Answer:
A). 15
B). -1.2
Step-by-step explanation:
A). [10(x+3)]-20 = 160
10x+30-20 = 160
10x+10 = 160
10x = 160-10
10x = 150
x = 150/10
x = 15
B). 5{[4(8+(5x))]-9} = 85
5(32+20x+9) = 85
5(32+9+20x) = 85
5(41+20x) = 85
205+100x = 85
100x = 85-205
100x = -120
100x/100 = -120/100
x = -1.2

Answer:
3rd one
Step-by-step explanation:
any 2 squares are congruent since all four sides of any square are congruent
-129 is the anwser to ur problem
Since we are solving for h, the equation:
V = πr²h
...divides πr² to the other side. Thus, it becomes....

= h
Which can be rewritten as....
h =
