Answer:
Step-by-step explanation:
I think you mean a^2 + 16a + 64.
The x-intercepts are the values of a for which the polynomial equals zero.
a^2 + 16a + 64 = (a+8)^2 = 0
a = 8
The x-intercept is 8.
Use the Please Exuse My Dear Aunt Sally method. Add what's in the parentheses first. (30) times 3 (90) - 3 = 77 ! Wait actually you are correct! No mistakes here!
The answer is C because It seems to be the most logical answer
We know that
applying the Pythagoras theorem
LM²=LV²+VM²
LM is the radius of the circle
LV=5 in
VM=12/2----> 6 in
so
LM²=5²+6²-----> LM²=61------> LM=7.81 in------> LM=7.8 in
the answer is
7.8 in
Do you have a diagram? But assuming x=5 is a side then you need another side and an angle in between the two sides
