zloy xaker [14]

Subtract 16,000 from 35,000 to find the quantity increase.

35,000 - 16,000 = 19,000

Now divide 19,000 by 16,000 to find the percent increase.

19,000 ÷ 16,000 = ‭1.1875‬

Multiply this by 100 to change it from a decimal to a percentage.

‭1.1875‬ × 100 = 118.75

<h2>Answer:</h2>

<u>Amir received a </u><u>118.75%</u><u> raise.</u>

How to factor that polynomial
professor190 [17]
<h3><u>(1 + 5y)(1 - 5y) is the fully factored form of this polynomial.</u></h3>

This polynomial can be factored using difference of squares.

This polynomial is in the form of a^2 - b^2 = (a + b)(a - b)

Because 1 * 1 = 1, we can use this formula to simplify this polynomial.

1 - 25y^2 = (1 + 5y)(1 - 5y)

We can use FOIL to verify this.

(1 + 5y)(1 - 5y)

1 - 5y + 5y - 25y^2

1 - 25y^2
