only one type of triangle has one line of summatry because you can fold it in half and they match.

Answer:

For the triangle all of whose sides have length 3, a proper fold through any vertex can serve as a line of symmetry and so there are three possible lines. The triangle with side lengths 2,4,5 cannot have any lines of symmetry as the side lengths are all different.

√(2x-5)=1+√(x-3)

Ostrovityanka [42]

Answer:

x = 3 only

Step-by-step explanation:

$\sqrt{2x-5} =1+\sqrt{x-3}$

$\implies 2x-5=(1+\sqrt{x-3})^2\\\\ \implies 2x-5=x+2\sqrt{x-3} -2$

$\implies x-3=2\sqrt{x-3}$

$\implies (x-3)^2=(2\sqrt{x-3})^2$

$\implies x^2-6x+9=4x-12$

$\implies x^2-10x+21=0$

$\implies (x-3)(x-7)=0$

$\implies x=3, x=7$

Check by substituting found values of x into original equation:

$x=3 \implies \sqrt{2(3)-5} =1+\sqrt{3-3} \implies 1 = 1 \ \ \ \checkmark$

$x=7 \implies \sqrt{2(7)-5} =1+\sqrt{7-3} \implies 3\neq 2 \ \ \ \ incorrect$

There was 3/8 of a pie left in the fridge.daniel ate 1/4 of the leftover pie.how much of a pie did he have?

Leto [7]

You would find the common denominator which in this case is 8. You would change 1/4 to 2/8. Which means that Daniel ate 2/8 of the pie.
