Answer:
(p+5)(p-2)
Step-by-step explanation:
We are looking for two numbers that multiply to -10 (the rightmost number) and sum to 3 (the middle number)
These are 5 and -2
So we write
(p ____)(p ____)
and fill in the blanks
(p+5)(p-2)
Check by FOILing:
p^2 -2p + 5p -10
And combine the two middle terms.
p^2 + 3p - 10
Answer:
42
Step-by-step explanation:
The permutation formula is P(n, r) = n! / (n - r)!. We know that n = 7 and r = 2 so we can write:
7! / (7 - 2)!
= 7! / 5!
= 7 * 6 * 5 * 4 * 3 * 2 * 1 / 5 * 4 * 3 * 2 * 1
= 7 * 6 (5 * 4 * 3 * 2 * 1 cancels out)
= 42

Answer:
B. Lynden
Step-by-step explanation:
4(2x+2) - 2(x + 2) = 10 - 3(x +2)
To use the distributive property, you multiply the terms inside the parentheses by the number outside them.
8x + 8 - 2x - 4 = 10 - 3x - 6
A is wrong. Gregory used the addition property incorrectly. He should have gotten
4(2x + 2) + (x + 2) = 10
C is wrong. Whitney used the distributive property incorrectly. She made a mistake when distributing the -2 in -2(x + 2). She should have gotten
8x + 8 - 2x - 4 = 10 - 3x - 6
D is wrong. David combined like terms incorrectly. 10 and 3x are not like terms. He should have gotten
4(2x + 2) - 2(x + 2) = 4 - 3x
Rule: (x+8), (y-3)
