serg [7]

Answer:

B,C

Step-by-step explanation:

So all you have to do is use the pythagorean theorem to solve this (a²+b²=c²).

Plug in the two shorter sides for a and b and the long side for c. If both sides equal the same thing then it will make a right triangle.

A) 5²+6²=9²

25+36=81

61≠81

B) 0.25+1.44=1.69

C)49+576=625

D) 100+256≠361

E)1+4≠9

Solve 2x^2– 5= 3x with the quadratic formula
Gwar [14]

Answer:

see below

Step-by-step explanation:

2x^2-3x-5=0

Well a=2, b=-3, c=-5

x=\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)} }{2*2}\\\\ x_1=\frac{3+\sqrt{49} }{4} =\frac{3+7}{4} =\frac{10}{4} =\frac{5}{4} \\\\x_2=\frac{3-\sqrt{49} }{4} =\frac{3-7}{4}=\frac{-4}{4} =-1
