For this case, what you should keep in mind are the following considerations:
1) Rewrite the expressions correctly using the properties of the exponents: Addition, multiplication, division, subtraction and negative exponents.
2) Simplify the expression as much as possible.

Answer:
CM = 4
Step-by-step explanation:
set CM=x and BM=y AM= 7-y
right triangle BMC: x² = 5² - y² = 25 - y² ... (1)
right triangle AMC: x² = (4√2)² - (7-y)² = 32 - 49 +14y - y² = -17 + 14y -y² ...(2)
(1)-(2): 0 = 42 - 14y
14y = 42
y (BM) = 3
x² (CM²) = 25 - 3² = 16
x (CM) = 4 (height is positive)
Answer:
5a-25=70
5a=70+25
a=95/5
a=19
Step-by-step explanation:
since a(b+c) = ab+ac
Answer:
I think it might be C. I am not sure.
Answer:
The median of the list is 26.
Step-by-step explanation:
Since the <u>mode of the list is 26</u>, and so far we only have one occurrence of 26 in the list, we know that one of our unknowns must equal 26.
If we set x = 26, we can then s<u>olve for y using the arithmetic mean formula. </u>We are left with: .
Solving for y leaves us with y=43.
Finally, we can put the list in order and find the middle values. Since the two middle values are 26, the median of the list is 26.
