Answer:
10. 23
11. -17
12. 0
13. -4
14. -6
15. 4
Explanation:
10. 8+15= 23
11. -8-9= -17
12. 8-8= 0
13. -8+4= -4 (same as 4-8)
14. -10+4= -6 (same as 4-10)
15. 12-8= 4
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

so, the 2.5oz cake will be "x" calories, pheeew, she'll be taking in 900 - x less calories.
Answer:
Square is a kind of kite.
Step-by-step explanation:
Consider the provided information.
Kite is a flat shape with two pairs of sides and each pair is made of two adjacent sides that are equal in length.
Square has four equal sides and four equal angles of 90°
Square is a kind of kite because it has two pairs of equal adjacent side.
Hence, square is a kind of kite.
Answer: m∠W = 56
because UVWX is a rhombus
=> UV // WX
=> 2y + 2y - 68 = 180
<=> 4y = 248
<=> y = 62
=> m∠W = 2.62 - 68 = 56
