Answer:
C. It is just right.
Step-by-step explanation:
We want to compare the ratios ...
bags : liters = 15 : 2
and
bags : liters = 90 : 12
If we multiply the numbers of the first ratio by 6, we see they are identical to those in the second ratio:
(15)(6) : (2)(6) = 90 : 12
The ratio of bags to liters for Peggy's tea matches the ratio Kermit likes. He will think it is just right.
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>
Answer:
Step-by-step explanation:
a4= 3 then a4-1= -1
an= a4-1 + ×
X= an - a4-1
X= 3-(-1) = 4
The recurcive formula is
An= an-1 + 4
The answer should be B
