Answer:
Given,
The total distance covered = 4 km,
Since, initially he would be in rest,
So, his starting point would be 0.
Now, his first break =
km,
Second break =
km,
Also, we can write,

Drawing number line:
Step 1: Draw a line.
Step 2: Make 12 marks in same distance.
Step 3: Starts from 0, then 1/3, 2/3, 3/3 and so on.
Thus, we can show Wayne's bike on a number line as below.
Answer:
-15
Step-by-step explanation:
We have the expression 3(2p - 5) - 6p and are asked to simplify.
Let's distribute, which is to multiply a number that is outside of a parenthesis bracket by the numbers inside the parenthesis.
3(2p - 5) - 6p
(3(2p) - 3(5)) - 6p
6p - 15 - 6p
Since you can only do changes to like terms and 15 and 6p are two different terms, we do 6p - 6p.
6p - 6p
0
Leaving us with -15.

Answer:
(x + 2)²
Step-by-step explanation:
Given
x² + 4x + 4 ← is a perfect square of the form
(x + a)² = x² + 2ax + a²
Compare like terms
a² = 4 ⇒ a =
= 2, thus
x² + 4x + 4 = (x + 2)²
