Answer:
40
Step-by-step explanation:
(120 - 40)/2 = 80/2 = 40
Answer:
84
Step-by-step explanation:
Given a quadratic equation in standard form, ax² + bx + c = 0 : a ≠ 0
Then the discriminant is Δ = b² - 4ac
2k² = 10k - 2 ( subtract 10k - 2 from both sides )
2k² - 10k + 2 = 0 ← in standard form
with a = 2, b = - 10 and c = 2, thus
b² - 4ac = (- 10)² - (4 × 2 × 2) = 100 - 16 = 84
Answer:
The answer to the problem is -4 the other answer is wrong

Let x, x + 1 two consecutive integers;
We have x + x + 1 = 185;
2x + 1 = 185;
2x = 184;
x = 92; x + 1 = 93;
92 < 93;
92 is the smaller of the two integers.
The volume is length * width * height. Length * width is 4 * 5 or 20, so we have that 20 * height = 200. Divide by 20 to get height = 10.
