Answer:

x=-\frac{3}{2} and x=5

Step-by-step explanation:

2x^2-7x-15=0

Factor by grouping.

(2x+3)(x-5)=0

Now apply the zero property

2x+3=0\\2x=-3\\x=-\frac{3}{2}

and

x-5=0\\x=5

Hello,

Step-by-step explanation:

2x² - 7x - 15 = (x - 5) (2x + 3)

x - 5 = 0 ⇔ x = 5

2x + 3 = 0 ⇔ x = -3/2

icang [17]

Answer:

the sum is 360 degrees, which means

360 = 124 + 124 + 2x + 2x

360 = 248 + 4x

-4x = 248 - 360

-4x = -112

x = 28

Check:

124 + 124 + 2(28) + 2(28) =

360

Your answer is x = 28
