Your answer should be 71. :)
The 18th sequence is - 41
Answer:
x = 2 or x = -2
Step-by-step explanation:
5x² - 15 = 5
⇌
5x² = 15 + 5
⇌
5x² = 20
⇌
x² = 20/5 = 4
⇌
x² = 2²
⇌
x² - 2² = 0
⇌
(x - 2)(x + 2) = 0
⇌ we use the zero product property
x - 2 = 0 or x + 2 = 0
⇌
x = 2 or x = -2
we know that
<u>The Division Property of Equality</u> states that if you divide both sides of an equation by the same number, both sides of the equation will remain equal
so
in this problem we have

Solve for x
Using the Division Property of Equality, Divide by
both sides


therefore
<u>the answer is the option</u>
c. 2y/5 ( 2y over 5 )
