Which of the following events has a probability of 1? Check all that apply.
landing on a blue or red space on a spinner with 1 blue space and 1 red space
choosing a red marble from a bag containing red and green marbles
drawing a peanut from a bag of trail mix with 4 types of nuts
drawing a red card from a stack of 20 red cards
getting a heads or a tails when flipping a coin
(x + 2)(x + 5)
for factored form you have to determine what two numbers multiplied by each other equal c that also, when added to each other, equal b.
y= ax^2 + bx + c
the factors of 10 are 1, 2, 5, 10
and 2 + 5 = 7
and in factored form with a = 1
(x + 5)(x + 7)
answer: x=10 y=10
the answer is 1200
10x - 5x = 6000
10(1200) - 5(1200) = 6000
