Answer:
That shape orientation changes.
Hello :
by identity : (a-b)² = a² +b² -2ab
(x√7-3√8)(x√7-3√8) = (x√7-3√8)² = (x√7)²+(3√8)² -2(x√7)(3√8)
=7x²+72 -6x√56
= 7x²+72-6x√(14×4)
= 7x²+72-12x√(14).because :√(14×4)=2√14
Answer B
The longest angle in a triangle is opposite the longest side. Similarly, the shortest angle in a triangle is opposite the shortest side. Knowing that...
<ACB is opposite to AB
<ABC is opposite to AC
<BAC is opposite to CB
We know that...
m<ACB < m<ABC < m<BAC
answer: m<ACB < m<ABC < m<BAC
Answer:
b = -6
Step-by-step explanation:
We use the general equation a*x^2 + bx + c = 0, the Quadratic Equation.
Compare it to 2x^2 - 6x - 20 = 0
b = -6 here
