Answer:
D
Step-by-step explanation:
(2x + 2) -
(3x - 1) = 15
multiply through by 4 ( the LCM of 2 and 4 ) to clear the fractions
2(2x + 2) - (3x - 1) = 60 ← distribute parenthesis and simplify left side
4x + 4 - 3x + 1 = 60
x + 5 = 60 ( subtract 5 from both sides )
x = 55
True.
Integration is also called anti-differentiation, mathematically its an inverse function of differentiation.
For example, one of the first equalities learned is:
.
Which explains that if you differentiate a function (get its derivative) and then integrate the derivative you will obtain the original function.

The length of the table is 15.14 inches.
<u>Given the following data:</u>
Translating the word problem into an algebraic equation, we have;
W = L - 8
To find the length of the table;
Mathematically, the area of a rectangle is given by the formula;
Substituting the values into the formula, we have;
Solving the quadratic equation by using the quadratic formula, we have the following values;
L = 15.14 or -7.14
We would choose the positive value.
Therefore, the length of the table is 15.14 inches.
