Find an expression for the nth term -3 , 2 , 7, 12​
slavikrds [6]

Answer:

5n-8

Step-by-step explanation:

Because this is an arithmetic progression, there is simply an addend that is being added to every number. Because that is 5, the expression, for now, would be 5n. However, the progression does not start at 0, so we will have to subtract 3, and then it would be 5n - 3. We're still not at the answer; this is because the first term starts at 1, not 0. We will have to account for that, so subtract the coefficient, or 5, from the whole expression. That would be 5n - 8, and that would be the answer.

Divide (-3х + 4 + 18х^2 )by (5 + 6x)
Leokris [45]

Answer:

The division will be represented as:

\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}

Step-by-step explanation:

1) Let's find a number with a variable that multiplied by 6x gives as 18x². It will be 3x, because (6x+5)3x=18x²+15x.

Now, let's subtstract:

(18x^{2}-3x+4)-(18x^{2}+15x)=-18x+4

2) Let's find a number with a variable that multiplied by 6x gives as -18x. It will be -3, because (6x+5)(-3)=-18x-15.

Now, let's subtstract:

(-18x+4)-(-18x-15)=19  

Therefore, the division will be represented as:

\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}

I hope it helps you!

What is the area of the rectangular piece of wood?
Mama L [17]

Answer:

2x^2 + 7x + 3 is the area of the rectangular piece of wood.

Step-by-step explanation:

Here,

Length ( l ) = x + 3

Breadth ( b ) = 2x + 1

Formula : -

Ar ( rectangle ) = lb

lb

= ( x + 3 ) ( 2x + 1 )

= x ( 2x + 1 ) + 3 ( 2x + 1 )

= 2x^2 + x + 6x + 3

= 2x^2 + 7x + 3
