Answer:
1.A,B,C,D
2. AB, CD
3. AC, BD
4. Line AD (don't take my word for this one)
Step-by-step explanation:
Since they are both even, let x and x + 2 be the integers.
x(x + 2) = 48
x² + 2x - 48 = 0
(x - 6)(x + 8) = 0
So, at x = 6 and x = -8.
So you can have 6 and 8 or -8 and -6 as your two integers.
Answer:
$14
Step-by-step explanation:
6 attendees divided by the cost of 12 = $2 per attendee
If 7 attendees are joining times $2 per person =$14
Answer:
B
Step-by-step explanation:
For three side lengths to make a triangle, the two smaller ones have to add up to be greater than the third one. This is because if they are any smaller, they won't be able to touch and form a triangle. The formula for this is a+b>c.
You can go through each answer choice and determine whether or not it would work:
A. 12, 5, and 7
5 + 7 > 12 --> 12 > 12 (NOT true)
B. 10, 15, and 24
10 + 15 > 24 --> 25 > 24 (true!)
C. 9, 22, 11
11 + 9 > 22 --> 20 > 22 (NOT true)
D. 21, 7, and 6
7 + 6 > 21 --> 13 > 21 (NOT true)
This means that the correct answer is B.
Answer:
Step-by-step explanation:
equation as 100−y2=x 100 - y 2 = x . Subtract 100 100 from both sides of the equation. Multiply each term in −y2=x−100 - y 2 = x - 100 by −1 - 1
