What is the answer to thiss

lana [24]

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression. So let's plug in the values and solve.

<u>Plug in the values</u>

$m^2 + 5$

$(9)^2 + 5$

<u>Factor out the exponent</u>

$(9*9) + 5$

$81 + 5$

<u>Combine</u>

$86$

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.

Solve for b:<br><br> b² = 8b + 84

levacccp [35]

B² = 8b + 84
b² - 8b - 84 = 0
b = <u>-(-8) +/- √((8)² - 4(1)(-84))</u>
   2(1)<u>
</u>b = <u>8 +/- √(64 + 336)</u>
   2
b = <u>8 +/- √(400)
</u>    2<u>
</u>b = <u>8 +/- 20
</u> 2
b = 4 <u>+</u> 10
b = 4 + 10 b = 4 - 10
b = 14 b = -6
