ave tried I don't know if its correct
Answer:

Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer: I assume the radius is 1/2 the base of 6 in.
r = 3 ft
h = 10 ft
s = 10.4403 ft
V = 94.2478 ft³
L = 98.3976 ft²
B = 28.2743 ft²
A = 126.672 ft²
r = radius
h = height
s = slant height
V = volume
L = lateral surface area
<span>B = base surface area </span>
A = total surface area
π<span> = pi = 3.14159</span>
<span>√ = square root</span>
Based on the given parameters, bhe true statements are: the expression has four terms, and the term -40/y is a ratio.
<h3>How to determine the true statements?</h3>
The expression is given as:
6x^3 - 8x^2 - 40/y + 21
The above expression has four terms, and the terms are:
6x^3, - 8x^2,- 40/y and 21
Also, the term -40/y is a ratio
This is so because it is a quotient of two numbers
Hence, the true statements are: the expression has four terms, and the term -40/y is a ratio, based on the given parameters
