Answer:
B = 10.5
Step-by-step explanation:
From the figures, it looks like triangle HER is similar to triangle KPS.
From that we get


Multiply both sides by 7.
B = 10.5
3n + n = 180
4n = 180
n = 180/4
n = 45
hope it helps, brainliest pls!
0 it is at ocean level so elevation is zero
A: One solution- a=11 b=5
B: Has no solution- a=10 b=5
C: Infinite solution- a=10 b=-8
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>
<u>Factor out the exponent</u>
<u>Combine</u>
Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
