Answer:
constant = -12
Step-by-step explanation:
Let the given equation be
2x² + 8x - 12 = 0 --------(1)
Here B² =(2√2)^2 = 8
Add 8 in both sides of (1)
Step1 : 2x² + 8x + 4 = 12 + 4
Step 2: x² + 4x + 4 = 16
step 3 : x² + 4x + 4 - 16 = 0
Step 4: x² + 4x - 12 = 0 ---(4)
From the (4) we get constant = -12
Answer:
Because emojis can better express what you are feeling, and it's fun to use. As for fairys... I don't really know either.
Step-by-step explanation
Answer:
+) m∠1 = m∠2 (vertical angles theorem)
+) m∠2 and ∠3 are supplementary (because a//b)
+)m∠3 = m∠4 (alternate interior angles theorem, c//d)
=> ∠1 and ∠4 are supplementary (substitution property of equality)
Step-by-step explanation:
Answer:
1) 36
2) 190
3) 72 units
Step-by-step explanation:
1) 2x4 = 8 units area for rectangle
(4-2) x4 /2 = 4 units
6 x 4 = 24 units
8 + 4 + 24 = 36
2) 3 x 10 / 2 = 15 units
5 x 10 /2 = 25 units
15 x 10 = 150 units
150 + 25 + 15 = 190 units
3) 6 x 3 / 2 = 9 units
6 x 9 = 54 units
6 x 3 / 2 = 9 units
9 + 9 + 54 = 18 + 54 = 72 units
