Answer:
Step-by-step explanation:
at the most two,
otherwise 2,1 or 0
I assume the equation is
√(2x - 5) - √(x + 6) = 0
Note the domains for the root expressions:
• √(2x - 5) : 2x - 5 ≥ 0 ⇒ x ≥ 5/2
• √(x + 6) : x + 6 ≥ 0 ⇒ x ≥ -6
So any valid solution we find must be at least 5/2.
Move one term to the other side.
√(2x - 5) = √(x + 6)
Take squares.
(√(2x - 5))² = (√(x + 6))²
2x - 5 = x + 6
Solve for x :
x = 11
Step-by-step explanation:
D because the angles add up to 90
A because both sets of angles add up to 180
Yes it is because if you multiply 3*3=9
then what you do on top you do on the bottom 10*3=30
