Answer:

$-x^2+2x-3$

Step-by-step explanation:

The given polynomial expression is

$(x^2-3x)+(-2x^2+5x-3)$

We regroup the terms in the polynomial to obtain;

$x^2-2x^2-3x+5x-3$

We combine like terms to get;

$-x^2+2x-3$

When we arrange the terms in the polynomial in descending powers of x, then we say it is in standard form.

The simplified polynomial in standard form is $-x^2+2x-3$

Dean put together first boxes for 5 of his neighbors. Each box cost $1.00 and contained a plant and a $3.00 pair of gardening gl

Scorpion4ik [409]

(5 Neighbors) x (($1.00 Box) + (? Plant) + ($3.00 Gloves)) = 42.50

5 x (1 + x + 3) = 42.50

Combine in parens.

5 x (4 + x) = 42.50

Distribute.

20 + 5x = 42.50

Subtract 20 from both sides.

5x = 22.50

Divide both sides by 5.

x = 4.50

Thats the cost of each plant.

Check.

5 x (1 + 4.50 + 3)

5 x 8.50 = 42.50
