Answer:
- Prime: 3
- GCF: 1
- Factoring Trinomials: 4
- Difference of Squares: 2
- Perfect Square Trinomial (PST): 5
Step-by-step explanation:
1. Each term has an even coefficient, so a factor of 2 can be removed:
2(3x^2 +7x -15)
The remaining quadratic factor is prime.
__
2. Each of these two terms is a square, so this is the difference of two squares.
__
3. This cubic has one irrational negative real root. It is prime.
__
4. This trinomial factors in the usual way: (x +15)(x -2). It is factored by "factoring trinomials."
__
5. The magnitude of the x-coefficient is double the square root of the (positive) constant, so this is a perfect square trinomial.
Answer:
Subtraction property of equality
Step-by-step explanation:
In the equation, 5 is subtracted from both the sides
Answer:
$8.45
Step-by-step explanation:
if he has $26 to start and spends 17.55 on his friends, he has 8.45 leftover to spend on himself, but since he bought his friends pancakes for 17.55 their pancakes would have cost 8.775 each which suggests that Jeremiah likely cannot afford his own pancakes
Answer:
0.10(n)=25+0.05(n-200)
Step-by-step explanation:
The number of business cards are n
Plan A: No initial fee and $0.10 for each business card
Plan B: $25 for the first 200 business cards
and surplus of $0.05 for each additional card
As n is total business cards
so from plan A equation is
0.10(n)
from plan B
25 + 0.05(n-200)
if n > 200
Now as a whole the equation for no of business cards would be
0.10(n)=25+0.05(n-200)
