Answer: w = 1/2 and w = -4

Step-by-step explanation:

2w^2+7w-4=0

The quadratic formula is (-b+ - √b^2-4ac)/2a

In this case a=2, b=7, c= -4

(-7+ - √7^2 - 4(2)(-4))/2(2)

(-7+ - √49+32)/4

(-7+ - √81)/4

(-7+9)/4 and (-7-9)/4

2/4 and -16/4

1/2 and -4

How do i solve this

Brilliant_brown [7]

Answer:

m <E = 134

Step-by-step explanation:

Triangle DEF looks like an isosceles triangle to the base angles are the same measure.

6x+11 = 10x+3

Subtract 11 from both sides

6x = 10x-8

Subtract 10x from both sides

-4x = -8

Divide -4 from both sides

x = 2

Substitute 2 into both equations to make sure it works

6 (2) + 11

12+11

10 (2) +3

20+3

Both angles equal 23 degrees.

Now subtract both angles from the total angle measure of 180.

180-23-23=134
