Step-by-step explanation:
He'll spend 138.91 dollars.
First multiply 427 and 231 to find out how much square feet you need to cover. Then divide the number by 3500 to see how many bags of fertilizer you need. Since there is a remainder, he'll have to buy another bag. Then, multiply the number of bags needed with the price of each bag to get the amount of money spent.
B: -5, -2
C: 5, 2, -4
D: 5, -2, -4
The solution is, A) 5, 2 are the coefficients in the polynomial 5x^2 + 2x - 4.
Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.
here, we have,
given that,
the polynomial is : 5x^2 + 2x - 4
now, we have to find the coefficients in the polynomial 5x^2 + 2x - 4
we know that,
a coefficient is a multiplicative factor in some term of a polynomial, a series, or an expression; it is usually a number, but may be any expression. When the coefficients are themselves variables, they may also be called parameters.
and. we have,
a variable is a symbol that represents a mathematical object. A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set.
so, we get,
a coefficient is the number in front of the variable,
here, 5, 2 are the coefficients.
and the variable is x.
Hence, The solution is, A) 5, 2 are the coefficients in the polynomial 5x^2 + 2x - 4.

Answer:
c
Step-by-step explanation:
The sales tax on an item costing $5 with a tax rate of 5.4% will be $0.27. This is calculated by converting the percentage to a decimal (0.054) and multiplying by the original cost ($5).
The subject of this question is mathematics, specifically, it's a problem of calculating the sales tax. In this scenario, if the tax rate is 5.4% and the initial price of the item is $5, you can calculate the amount of tax to pay by multiplying the original price of the item by the tax rate in decimal form.
So, step 1 is converting the percentage into a decimal by dividing by 100. That gives us 5.4 / 100 = 0.054.
Step 2 is multiplying this tax rate by the original price of the item: $5 * 0.054 = $0.27.
Therefore, the tax you would pay on an item that costs $5 before sales tax is approximately $0.27, rounding up to the nearest cent.
