Answer: C
Step-by-step explanation: a^2 + b^2 = c^2
A. 6^2 + 8^2 = 10^2
B. 12^2 + 35^2 = 37^2
C. 4^2 + 6^2 does not equal 10^2.....(16 + 36 = 52 10^2 = 100)
D. 10^2 + 24^2 = 26^2
7/8, 1 is also 8/8 so if you add that to -1/8 (then it automatically subtracts since it’s adding a negative) making 7/8.
Hello,
Answer:
S = { -0,42 ; 2,71 }
Step-by-step explanation:
7x² - 16x = 8 ⇔ 7x² - 16x - 8 = 0
a = 7 ; b = -16 ; c = -8
Δ = b² - 4ac = (-16)² - 4 × 7 × (-8) = 480 > 0
x₁ = (-b - √Δ)/2a = (16 - √480)/14 ≈ -0,42
x₂ = (-b + √Δ)/2a = (16 + √480)/14 ≈ 2,71
