Answer:
x < -12
Step-by-step explanation:
−21x>6
Multiply both sides by -2(−2)2−1x>(−2)6
Simplify - remember to flip the inequality symbolx<−12
Graph: ←-----------o -12
Interval Notation: (-∞, -12)
There is 2 ways to solve this type of question.
Method 1
--------------------------------------------------
Formula
--------------------------------------------------
a² + b² = c²
--------------------------------------------------
Apply the formula
---------------------------------------------------
(7√2)² + (7√2)² = c²
c² = 98 + 98
c² = 196
c = √196
c = 14
--------------------------------------------------
Ans: The diagonal length is 14cm
--------------------------------------------------

Method 2
--------------------------------------------------
Identify the triangle
--------------------------------------------------
This is a special triangle
45° - 45° - 90°
--------------------------------------------------
Property of the Angles
--------------------------------------------------
x - x - x√2
--------------------------------------------------
Find hypotenuse
--------------------------------------------------
Given that the non-hypotenuse is 7√2
Hypotenuse = (7√2)(√2)
Hypotenuse = 7 x 2
Hypotenuse = = 14cm
--------------------------------------------------
Ans: The diagonal length is 14cm
--------------------------------------------------
Answer: 8
Step-by-step explanation: To find the least common multiple or (lcm) of 4 and 8, let's begin by listing the first few multiples of each number.
<em><u>Multiples of 4</u></em>
1 × 4 ≈ 4
2 × 4 ≈ 8
3 × 4 ≈ 12
4 × 4 ≈ 16
Notice that we skipped 0 × 6 in our list of multiples and this is because 0 × 4 is equal to 0 and our least common multiple can't be 0.
Now, let's list the multiples of 8. When listing the multiples of 8, it's a good idea to keep an eye on the list of multiples for 4 so that we will notice when we find a least common multiple.
<u><em>Multiples for 8</em></u>
1 × 8 = 8 ← is a multiple of 4
Notice that we can stop here because all other multiples that we find will be greater than 8. Therefore, the least common multiple or (lcm) of 4 and 8 is 8.
Answer:
The line segment's position changes, but its length remains the same.
Step-by-step explanation:
When a line segment is translated, it only will move its position up, down, or to the side.
The slope and length will stay the same, but the position will change.
So, this answer is correct because the position changes but not the length.
