Which is a solution to (x – 3)(x + 9) = –27? x = –9 x = –3 x = 0 x = 6

likoan [24]

Answer:

x = 0

Step-by-step explanation:

Since the product is not equal zero, we need to multiply both parenthesis first:

$(x-3)(x+9) =-27$

$x*x+x*9+(-3)*x+(-3)*9=27$

$x^2+9x-3x-27=27$

$x^2+6x-27=27$

Add 27 from both sides:

$x^2+6x-27+27=-27+27$

$x^2-6x=0$

Factor $x$ out:

$x(x+6)=0$

Apply the zero product:

$x=0,x+6=0$

$x=0,x=-6$

The solutions of the equation are $x=0$ and $x=-6$ .

We can conclude that the correct answer is x = 0.

Three farmers shared an order for fertiliser between them in the ratio 3:4:7.

Viktor [21]

Answer:

45 kg = Bethan's share

105 kg = Jade's share

Step-by-step explanation:

Let 3x = Bethan's share

4x = Noah's share

7x = Jade's share

Since Noah's share was 60, then 4x = 60

x = 15

3(15) = 45 kg = Bethan's share

7(15) = 105 kg = Jade's share
