Zack sells full-grown ostriches for $925 and full-grown llamas for $890 each. Zack sold one less than twice as many llamas as os

triches this year. His total sales for the year were $23,455. How many llamas did Zach sell during this year?

23.455 = 890 * (2x - 1) + 925x
23.455 = 1780x - 890 + 925x
23.455 = 2705x - 890
24.345 = 2705x
x = 9

1. In algebra, like terms are terms that have the same variables and powers.

2. What is combining like terms? We call terms "like terms" if they have the same variable part.

3. Polynomials form a system similar to the system of integers, in that polynomials are closed under the operations of addition, subtraction, and multiplication. CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial. ... Polynomials are closed under subtraction.

Hope this helps

Solve 3x2 = −12x − 15.<br><br> x = −4 ± 2i<br> x = −4 ± i<br> x = −2 ± 2i<br> x = −2 ± i

diamong [38]

ANSWER

$x = - 2 \pm i$

EXPLANATION

We use the method of completing the squares.

The equation is
$3 {x}^{2} = - 12x - 15$

We rewrite the above equation to obtain;

$3 {x}^{2} + 12x = - 15$

We divide through by 3 to obtain;

${x}^{2} + 4x = - 5$

We add half the coefficient of
$x$

to both sides of the equation to get,

${x}^{2} + 4x + {2}^{2} = - 5 + {2}^{2}$

The right hand side is now a perfect square.

${(x + 2)}^{2} = - 1$

We now take square root of both sides to get;

$x + 2 = \pm \sqrt{ - 1}$

We add -2 to both sides,

$x = - 2 \pm \sqrt{ - 1}$

We simplify to obtain,

$x = - 2 \pm i$
