The Gutierrez family and the Kim family both have pools. The Gutierrez family is filling their pool, which is modeled by the equation =
1
2 + 1. The Kim family is draining their pool,
which is modeled by the equation = −1.25 + 5. In both equations, represents the time in
hours and represents the depth of the water in the pool in feet. These two situations can be
described by the following system of equations:

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"
