4. Find the value of n that makes this equation true. (Use

andreyandreev [35.5K]

Answer:

$n=4$

Step-by-step explanation:

We start off with 3.2n + 13.3 = 26.1.

We need to get n by itself.

Subtract 13.3 from both sides.

$3.2n+13.3-13.3=26.1-13.3$

$26.1-13.3=12.8$

We end up with: $3.2n=12.8$

Divide 3.2 on both sides to get n by itself.

$\frac{3.2n}{3.2} =\frac{12.8}{3.2}\\ n=4$

(2a 2 + a + 3) (a - 1) Please help

ArbitrLikvidat [17]

Hey there!

You can use distributive property, as I mentioned in your previous questions.

multiply...
2a² × a = 2a³
2a² × -1 = -2a²
a × a = a²
a × -1 = -a
3 × a = 3a
3 × -1 = -3

add all those terms..
2a³ - 2a² + a² - a + 3a - 3
add the like terms

2a³ - a² + 2a - 3

Hope this helped :)
