Answer:
61.61
Step-by-step explanation:
In the expression now that we know the value of x and y, we can replace it with its values. So it would look like this.... 43.37 + 18.24. This equals 61.61.
Hope this helps!
Honestly just use desmos or mathyway
Answer:
Step-by-step explanation:
1. Area => 7.5 x 2 = 15 m² (Choice B)
2. Area => 5 x 11 = 55 in² (Choice B)
3. Area = (12 x 18) * 0.5 = 108 cm² (Choice A)
4. Triangular Pyramid (Choice D)
6. Area of Rectangle => 12 x 9 = 108
Area of Triangle => 7x6 = 42
Sum of Area => 150
7. Surface Area => (4x4)x6 = 96 in² (Choice D)
8. Volume = 3x15x14 = 630 in³ (Choice D)
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
