Step-by-step explanation:
it's an equilateral triangle so all sides are equal
using Pythagorean theorem
2(√6) raised to the power of 2 = √6 raised to the power of 2 + x raised to the power of 2
2(√6) raised to the power of 2 is 12
√6 raised to the power of 2 is 6
therefore 12=6 + x
x = 12-6
x=6
Answer:
a = 4.
Stepby-step explanation:
x^2 - 4 = (x + 2)(x - 2).
Answer:
11=x
Step-by-step explanation:
1) distribute the "2"
2x+14=36
2) subtract 14 on both sides
2x+14=36-14
2x=22
3) divide by 2 on both sides
2x/2=22/2
x=11
