(2x^3-5x^2+8)(x+3)=?

1 answer:

8 0

(2x³ - 5x² + 8)(x + 3) = ?
First step is to distribute.

2x^4 + 6x³ - 5x³ - 15x² + 8x + 24
Now combine like terms.

2x^4 + x³ - 15x² + 8x + 24

This is your answer, since you can't simplify any further or solve it without some more information.

lawyer [7]

Answer:

$C=10000(0.852)^t$

Step-by-step explanation:

Let the exponential function be,

$C=a(b)^t$

Here, C = cost of the car

t = Duration or period in years

From the given table,

Two points representing cost of the car and time are (10000, 0) and (8520, 1),

For (10000, 0),

$10000=a(b)^0$

a = 10000

For (8520, 1)

8520 = $10000(b)^1$

$b=\frac{8520}{10000}$

b = 0.8520

Therefore, exponential equation will be,

$C=10000(0.852)^t$

Let x be the amount of cement and y be the amount of sand. If the ratio of cement to sand for mortar is 1:3, then $\frac{x}{y} = \frac{1}{3}$ and y=3x.

So, if Sandy puts in x=7 shovels of cement, then she puts $y=3\cdot 7=21$ shovels of sand.

Answer: 21 shovels of sand.
