ANSWER
EXPLANATION
The given expression is
This is the same as:
In index notation, we write this as
To write this as a negative index, we use the property:
This implies that;
5(5r-7)=-185
25r - 35 = - 185
25r = - 150
r = - 6

Answer:
side length of sculpture = 9 cm
height of sculpture = 6cm
Step-by-step explanation:
Given that,
volume of sculpture = 162cm³
side length of sculpture = x
height of sculpture = x-3
formula for volume of sculpture
<h3>V=1/3 a²h</h3>
by putting values, the equation can be used to find the length of the sculpture’s base
162 = 1/3 (x)² (x-3)
162(3) = (x)² (x-3)
486 = x²(x-3)
486 = x³ - 3x²
x³ - 3x² - 486 = 0
x = 9 <em>(using a graph tool / calculator equation mode)</em>
side length of sculpture = 9 cm
height of sculpture = 9 - 3
= 6cm
