Answer:
55 And 57
Step-by-step explanation:
55, 56, 57,
Answer:
76
Step-by-step explanation:
given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0
then the discriminant is 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
3. you cannot simplify √30
12in=1ft
39/12=3.25ft
1m=3.25ft
times 4 both sides
4m=13ft
12ft
C
