The factors of 3x^2+10x+3 are (3x+1)(x+3)

Answer:

(3x+1)(x+3)

Step-by-step explanation:

We have been given an expression 3x^2+10x+3. We are asked to factor the given expression.

We will factor our given expression by splitting the middle term. We need two numbers which add up-to 10 and whose product is 9.

We know that 1 and 9 are such numbers.

3x^2+9x+1x+3

Make two groups:

(3x^2+9x)+(1x+3)

3x(x+3)+1(x+3)

(3x+1)(x+3)

Therefore, our required factors are (3x+1)(x+3) .

charity is four times as old as her daughter. she is also six years younger than her husband. The sum of their ages ten years to
Pachacha [2.7K]

Answer:

36years

Step-by-step explanation:

Let charity present age be x

Charity daughter present age be y

Charity husband present age be z

If the sum of their ages ten years to come is 117, then;

10+x+10+y+10+z = 117

30+x+y+z = 117

x+y+z = 87 ... 1

If charity is four times as old as her daughter, then;

x = 4y

y = x/4 ... 2

If she is also six years younger than her husband, then;

x = z- 6

z = x+6 .. 3

Substitute 2 and 3 into 1;

x + x/4 + (x+6) = 87

Multiply through by 4

4x + x + 4(x+6) = 4(87)

5x+4x+24 = 348

9x = 348 - 24

9x = 324

x = 324/9

x = 36

hence Charity is 36years old today
