If ab = c - d, which of the following is an expression for d in terms of a, b, and c?
horsena [70]
ANSWER

d =  - ab + c


EXPLANATION


The given expression is

ab = c - d

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.


This means that, we need to isolate d on one side of the equation while all other terms are on the other side.



We subtract from both sides of the equation to obtain,


ab - c = - d



We now divide through by -1, to get,



- ab  +  c = d


Or


d = - ab  +  c

Find the zeroes of the polynomial function f(x)=x^4-5x^3+11x^2-25x+30.
katen-ka-za [31]

Step-by-step explanation:

x⁴ − 5x³ + 11x² − 25x + 30

x⁴ − 5x³ + 6x² + 5x² − 25x + 30

x² (x² − 5x + 6) + 5 (x² − 5x + 6)

(x² + 5) (x² − 5x + 6)

(x² + 5) (x − 2) (x −3)

The zeros are 2, 3, and ±√5i.

The length of a rectangle is represented by the function L(x) = 5x. The width of that same rectangle is represented by the funct
Mazyrski [523]

Remember that the area of a rectangle is the length of the rectangle multiplied by the width of the rectangle.


In this case, we could say (where A(x) is the area of the rectangle):

A(x) = L(x) \cdot W(x)


Substituting the values the problem gave us for L(x) and W(x), we can find the formula for A in terms of x, which is:

A(x) = (5x) \cdot (2x^2 - 4x + 13) = (10x^3 - 20x^2 + 65x)


The formula for the area of the rectangle would be A(x) = 10x³ - 20x² + 65x.
