Answer:
Δ = 60
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c = 0 : a ≠ 0
Then the discriminant
Δ = b² - 4ac
Given
3x² + 6x = 2 ( subtract 2 from both sides )
3x² + 6x - 2 = 0 ← in standard form
with a = 3, b = 6 and c = - 2
b² - 4ac = 6² - (4 × 3 × - 2) = 36 - (- 24) = 36 + 24 = 60
A = (6 x 7) + 1/2(6 x 3)
= 42 + 9
= 51
answer
51 in^2
Answer:
1. Figure C has reflection symmetry.
2. A and D have reflection symmetry.
Step-by-step explanation:
1. When you cut the arrow horizontally, you get the same shape on each side.
2. When you divide them, you should have symmetry, meaning they are the same when divided/cut.
