Answer:
76
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0, then
the discriminant Δ = b² - 4ac
Given
3x² - 10x = - 2 ( add 2 to both sides )
3x² - 10x + 2 = 0 ← in standard form
with a = 3, b = - 10 and c = 2
b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76
Answer:
A the answer is the first one
break them apart put 18 into 10 and 8 and multiply it by 30 10 x 30 equals 300 30 x 8 equals 240 add them up you get 540 do the same with next one break 15 into 10 and 5 multiply 20 by 5 and you get 100 multiply 20 by 10 and you get 200 add them up and you get 300 now add the final numbers up and you get 840
