Answer: x³+2x²-15x

Step-by-step explanation:

1. Expand

(x²-3x)(x+5)

2. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd

x³+5x²−3x²−15x

3. Collect like terms

x³+(5x²−3x²)−15x

4. Simplify

x³+2x²-15x

Hope this helps, have a BLESSED and wonderful day! ;-)

What was the total production of gasoline and kerosene combined (in Barrels)

Elina [12.6K]

The amount of kerosene and gasoline produced is an illustration of equations.

44.4 million barrels of gasoline and kerosene are produced

Let

$x \to$ Proportion of kerosene

$y \to$ Proportion of Gasoline

So:

$x = 40\%$

$y = 34\%$

$Total = 60\ million$ ---- total barrels produced

The amount of Kerosene produced is:

$Kerosene =x \times Total$

$Kerosene =40\% \times 60\ million$

$Kerosene = 24\ million$

The amount of Gasoline produced is:

$Gasoline =y \times Total$

$Gasoline =34\% \times 60\ million$

$Gasoline =20.4\ million$

So, the total production of both is:

$Total = Kerosene + Gasolene$

$Total = 24\ million + 20.4\ million$

$Total = 44.4 million$

Hence, 44.4 million barrels of gasoline and kerosene are produced

I want to rearrange the formula of 3+x=ax to find out what x is equal to. I already know the answer via the answer sheet but I w

taurus [48]

Answer:

See below.

Step-by-step explanation:

$3+x=ax$ (Given)

$x=ax-3$ (Subtracted 3 on both sides)

$x-ax=-3$ (Subtracted ax on both sides)

$x(1-a)=-3$ (Factor out x from x - ax)

$x=-\frac{3}{1-a}$ (Divided 1 - a on both sides)
