First you simply have to substitute 2 in replace of all the a's, and -2 in replace of all of the b's
4((2)2+2(-2))
Then you want to follow the order of operations, PEMDAS (Parantheses-Exponent-Multiplication-Division-Addition-Subtraction), and multiply within the parantheses.
4(4+(-4))
Next you will add within the parantheses (So add the 4 and -4 together)
4(0)
Lastly multiply
0
Your answer is 0
Hope this helps!

The '68-95-99.7' rule says
-About 68% of values fall within one standard deviation of the mean.
-About 95% of the values fall within two standard deviations from the mean.
-Almost all of the values — about 99.7% — fall within three standard deviations from the mean.
Here ![31.4=29+2*1.2 26.6=29-2*1.2](https://tex.z-dn.net/?f=%2031.4%3D29%2B2%2A1.2%2026.6%3D29-2%2A1.2%20)
Therefore, the probability
![P(26.6](https://tex.z-dn.net/?f=%20P%2826.6%3CL%3C31.4%29%3D0.95%20)
The required probability

Answer:
-20x³ + 0x² + 15x - 20
Step-by-step explanation:
I would have said it the other way.
"Multiply each term in the top row by -5."
4x³ + 0x - 3x + 4
<u>×(-5</u>) <u>×(-5</u>) <u>×(-5)</u> <u>×(-5)
</u>
-20x³ + 0x² + 15x -20
