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

Oxana [17]

(x+3)(x+3) = x^2 -3 + 3x
x^2 + 3x + 3x + 9 = x^2 + 3x - 3
x^2 + 6x + 9 = x^2 + 3x - 3
6x + 9 = 3x - 3
3x + 9 = -3
3x = -12
x = -4

Check:
(-4+3)^2 = (-4)^2 - 3(1+4)
(-1)^2 = 16 - 3(5)
1 = 16-15
1 = 1 :)

Hey can you please help me posted picture of question

Nataliya [291]

Total number of blue candies = 20 + 30 = 50
Number of blue candies without nut = 20

Probability of picking a blue candy without a nut = (Number of blue candies with nut) /(Total number of blue candies)

So, Probability of picking a blue candy without a nut = $\frac{20}{50} =0.4=40$ %

Thus, the correct answer is option A
