Find the solutions to the equation below check all that apply 2x^2+11x+5=0 a. x=-3 b. x=4 c. x=2 d. x=-5 e. x=-1/2 f. x=3

Solution of the equation  are:

D. x= -5

E. x= -1/2

Step-by-step explanation:

We are given a equation:

Now, on solving the equation

Hence, (2x+1)(x+5)=0

⇒ either 2x+1=0  or x+5=0

⇒ either x= -1/2 or x= -5

Hence, solution of the equation  are:

D. x= -5

E. x= -1/2

10 you would take 50/ .2

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
