Answer:
9
Step-by-step explanation:
To find the common difference, take the second term and subtract the first term
13-4 =9
Lets check:
Take the third term and subtract the second term
22-13 =9
The common difference is 9
9 is the common difference between the numbers in this sequence
4 <em>+</em><em>9</em><em> </em>= 13
13 <em>+</em><em>9</em><em> </em>= 22
22 <em>+</em><em>9</em><em> </em>= 31
31 <em>+</em><em>9</em><em> </em>= 40
Therefore the common difference is <em>9</em>

d
100x² - 1 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
100x² - 1
= (10x)² - 1²
= (10x - 1)(10x + 1) → d
it should be 0.7
