The equation 4x2 + 8x + 15 = 0 is being rewritten in vertex form. Fill in the missing step.

Given4x2 + 8x + 15 = 0
Step 14(x2 + 2x ___) + 15 ___ = 0
Step 2✔
Step 34(x + 1)2 + 11 = 0
4(x2 + 2x + 1) + 15 − 4 = 0
4(x2 + 2x + 1) + 15 − 1 = 0
4(x2 + 2x + 2) + 15 − 2 = 0
4(x2 + 2x + 4) + 15 − 4 = 0

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
