Step-by-step explanation:
Step-by-step explanation:
First let us suppose the missing number x
I think we will cross multiply
5b2 = bx
5b2/b = bx
5b = x
Answer:
1/4
Step-by-step explanation:
.5/2=.25=1/4
Keep these rules in mind:
- (a + b)² = a² + 2ab + b²
- (a - b)² = a² - 2ab + b²
- (a + b)(a - b) = a² - b²
Firstly, solve the exponent and multiplication:

Next, combine like terms:

Next, subtract 4x² on both sides:

Next, subtract 25 on both sides:

Lastly, divide both sides by -20.5. And since you are dividing by a <u>negative</u>, flip the inequality sign:

<u>Your answer is x > 2.</u>
