Answer:

- 315

Step-by-step explanation:

Given a quadratic equation in standard form ax² + bx + c : a ≠ 0

Then the discriminant is

Δ = b² - 4ac

Given

3x² + 15x + 25 = - 3x - 2 ( subtract - 3x - 2 to both sides )

3x² + 18x + 27 = 0 ← in standard form

with a = 3, b = 18 and c = 27, then

b² - 4ac = 3² - (4 × 3 × 27) = 9 - 324 = - 315

Answer:

Option (A)

Step-by-step explanation:

AE and RV are the two line segments intersecting at a point N.

Therefore, ∠ANR ≅ ∠ENV [Vertical angles are equal in measure]

(8x + 12)° = (5x + 57)°

8x - 5x = 57 - 12

3x = 45

x = 15

Since, m∠ENV = 5(15) + 57

                        = 75 + 57

                        = 132°

Therefore, Option (A) will be the answer.

15) a) -3 and -4

-3(-4) = 12 (two negative numbers multiplied or divided together = positive answer)

      b) -5 and 6
6(-5) = -30 (one negative number and one positive number multiplied together = negative answer)
-5 + 6 = 1


16) 2.4 kg, 0.7 kg
c) a loss of 15kg should be your answer, because the loss has a larger number proportion than the gained
