Answer:
16 sqrt(30)
Step-by-step explanation:
2√20 × 4√6
Multiply
2*4 sqrt(20*6)
8 sqrt(120)
Simplifying
8 sqrt(4 *30)
We know sqrt(ab) = sqrt(a) sqrt(b)
8 sqrt(4) sqrt(30)
8 *2* sqrt(30)
16 sqrt(30)
Answer:
A. 18.2
Step-by-step explanation:
b^2 + 14^2 = 23^2
b = sqrt(333) = 18.248
Solution: Alyssa is incorrect.
In fact 
.
If we cross-multiply the above equation, we have:
Therefore, they are equal.
Also, if we reduce the given fractions, we have:
And
Since both the fractions reduced to 
, therefore fractions are equivalent.
Answer:
17
Step-by-step explanation:
6^2 + y^2 = 10^2
36 + y^2 = 100
y^2 = 64
y = 8
y^2 + 15^2 = x^2
64 + 225 = x^2
289 = x^2
x = 17
