So first you want to do the cost of each foot times the number of feet 112 * $1.59 = $178.08

Then do the subtraction $200.00 - $178.08 = $21.92

Therefore, the answer is C

Write an expression with a negative exponent that has a value between 0 and 1/2
aliya0001 [1]
<span>Exponent is a number used to express shorter equation; it is a number that says how many times you are going to multiply the base number.
</span><span>
Exponents have several laws, here are some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n

And since we were asked to write an expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½

Help me please!!!!!!!!!

Answer:

(x + 1)(5x - 3)

Step-by-step explanation:

Given

5x² + 2x - 3

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term, that is

product = 5 × - 3 = - 15 and sum = + 2

The factors are + 5 and - 3

Use these factors to split the x- term

5x² + 5x - 3x - 3 ( factor the first/second and third/fourth terms )

= 5x(x + 1) - 3(x + 1) ← factor out (x + 1) from each term

= (x + 1)(5x - 3) ← in factored form
