<em>1.10+9=19</em>

<em>2.11+8=19 </em>

<em>3.2(9)+1=19</em> (2(9)=18+1=19)

<em>4. 3(6)=1=19</em> (3(6)=18+1=19)

find three consecutive integers. such that 4 times of first integer is 18 more than the sum of the second and third integer
Juliette [100K]

Three consecutive numbers are x, x+1 and x+2.

Four times the first integer is 4x

The sum of the second and third is (x+1)+(x+2)=2x+3.

So, we have

4x = 2x+3+18\iff 4x=2x+21

Subtract 2x from both sides:

2x=21

Divide both sides by 2:

x=10.5

So, you can't have three consecutive integers such that four times the first is 18 more than the sum of the other two: the three numbers would be 10.5, 11.5, 12.5.

In fact, you have

4\cdot 10.5 = 42

and

11.5+12.5+18 = 24+18=42

3x to the power of 3 + 21x squared + 36x = 0 by factoring the quadratic equation.
Diano4ka-milaya [45]

Answer:

x = 0, -4 and -3.

Step-by-step explanation:

The given expression is "3x to the power of 3 + 21x squared + 36x = 0".

We can write this expression as follows :

3x^3+21x^2+36x=0

Taking 3x common.

3x(x^2+7x+12)=0\\\\3x=0\ \text{and}\ (x^2+7x+12)=0

x = 3

x^2+7x+12=0\\\\x^2+3x+4x+12=0\\\\x(x+3)+4(x+3)=0\\\\(x+4)(x+3)=0\\\\x=-4,-3

Hence, the solution of the given quadratic equation are x = 0, -4 and -3.
