(x + 9)(x + 12) = 0
Expanding the brackets, we get:
1) |−11| = 11, therefore Peter is at a distance of 11 feet
2) Jimmy, because each of the two points is fraction 5 over 8 unit away from 0
3) 36 + 28=64 4x4=36+4x7=28 36+28=64
7+9=16 4x16=64
4/5, because to simplify a decimal, you can divide the numerator by the denominator. 4 divided by 5 is 0.8
That represents exponential growth because we are multiplying by 2.1 every time. Since you are multiplying by a number greater than 1 that means that the number is getting bigger as x gets bigger. This means that we have exponential growth.
