The line is stretched from M to P
The point O is in between M and P, so the length OM add length OP will give the full length of MP
OM =
OP =
The length MP = OM + OP =
If N is the midpoint of MP, then the length MN is half of the length MP
MN =
Hello!
1. -4x2 + 8x + 32
-4(x2 - 2x - 8)
-4(x2 + 2x - 4x - 8)
-4(x(x + 2) - 4(x + 2))
-4(x + 2)(x - 4)
Answer A.
2. 2x2 + 16x + 30
2(x2 + 8x + 15)
2(x2 + 5x + 3x + 15)
2(x(x + 5) + 3(x + 5))
2(x + 5)(x + 3)
Answer C.
There is a 1 in four chance of rolling those 3 numbers. You know this because there is a 3/12 chance of of rolling a 10,11, or 12. Simplify the fraction and you get 1/4.
Answer:
I don't know if u want to know ask ur parents
Answer: a. Positive, because the products (3)(-3) and (-2)(4) are negative, and the product of two negative numbers is positive
Step-by-step explanation: It is also possible to rearrange the factors.
(3)(4) = 12 a positive number.
(-3)(-2) = 6, a positive number. Again "a negative times a negative is a positive" --Jaime Escalante, <em>Stand and Deliver</em>
Now you have two positive numbers: 12×6 = 72
The product is positive either way.
