Answer:
C
Step-by-step explanation:
For every 5 cashews, there are 6 peanuts and 7 almonds.
Means: Cashews:Peanuts:Almonds = 5:6:7
Sum of ratio = 5 + 6 +7 = 18
Cashews = (5/18) * 270 = 75
Peanuts = (6/18) * 270 = 90
Almonds = (7/18) * 270 = 105
So how many more what are there than peanuts?
The number of that nuts Minus the number of peanuts.
= Number of that nuts - 90
Answer:
d. only the first equation is an identity
Step-by-step explanation:
The first one is A because 8/100times 2 equals 16/200
Answer:
see explanation
Step-by-step explanation:
Given
- 16 ← difference of 2 squares and factors in general as
a² - b² = (a - b)(a + b)
- 16
= (p² )² - 4²
= (p² - 4)(p² + 4) ← (p² - 4) is also a difference of squares
= (p - 2)(p + 2)(p² + 4)
