Simplify the expression by combining like terms. Write the terms from the highest to the
lowest power of the variable.
6b2 + 3b2 + 86 - 9 + 24b2 - 14 - 5b - 4b

Will give brainliest series to sigma notation write the following series in sigma notation. 6+10+14+18+22+26+30 example image shown below.

Answer this question! 30 points and brainliest! only if you know the answer.

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases
