mash [69]

Answer:

Step-by-step explanation:

2x*2x=4x^2

2x*3=6x

Keep in mind 4x^2-6x

then next part:

3*2x=6x

3*3=9

6x-9

So totally

(4x^2-6x)-(6x-9)

Minus and minus is equal to +

(4x^2-12x+9)+2=45

4x^2-12x+11=45

-11 on both sides

4x^2-12x=34

X= -17/-2

Firewood is stacked in a pile. The bottom row has 20 logs, and the top row was 14 logs. Each row has one more log than the row a
Lyrx [107]

Since, each row has one more log than the row above it

so, this is arithematic sequence

We are given that

First row is

=14

so,

a_1=14

Last row is

=20

so,

a_n=14

Each row has one more log than the row above it

so,

d=1

now, we can find number of rows

a_n=a_1+(n-1)d

we can plug values

20=14+(n-1)1

we can solve for n

6=(n-1)1

n=7

now, we can find total number of logs

S=\frac{n(a_1+a_n)}{2}

now, we can plug values

S=\frac{7(14+20)}{2}

S=\frac{7(14+20)}{2}

S=119

So,

Number of logs in the pile are 119........Answer
