If there are parentheses you add the exponent on the outside to the exponents inside that belong to a variable.
For the three you would just cube it regularly, but for the x you would add the 3 to the 2 that is already on the x
To find SN you need to find the value of x then solve 6x+1
<span>The inequality |2x − 6| less than or equal to 10 can be expressed as two form like this to get two value of x
2x-6 </span>≤<span> 10
2x</span>≤10+6
x≤8<span>
-(</span>2x-6) ≤ 10<span>
2x-6 </span>≥<span> -10
2x</span>≥-10+6
x≥-4
<span>
The graph of the inequality would be: </span>
x≤8 and x≥-4
or
-4≤x≤8
Difference of two squares:
(a+b)(a-b) = a² - b²
(a-b)(a+b) = a² - b²
The difference of two squares results to a binomial because the middle term cancels each other out.
example:
a = 2 ; b = 3
(2 - 3)(2 + 3) = 2(2+3)-3(2+3) = 4+6-6+9 = 4 + 0 + 9 = 4 + 9
The gallons needed to paint the silo is 10.

A cylinder is a three-dimensional object. It is a prism with a circular base. The total surface area of cylinder can be determined by adding the area of all its faces.
Total surface area of the cylinder excluding its base = 2πrh +πr²
Where:
TSA = (2 x 3.14 x 10 x 30) + (3.14 x 10²)
314 + 1884 = 2198 ft²
Number of gallons needed = 2198 / 224 = 9.81 = 10 gallons
