5 0

Answer:

D. This quadratic equation two complex solutions.

Step-by-step explanation:

5x^2 +6x +2= 0\\

Equating it with

ax^2 +bx +c= 0\\

a = 5, b = 6, c = 2

b^2 -4ac\\= 6^2 - 4\times 5\times 2\\= 36-40\\b^2 -4ac= - 4\\

\because b^2 -4ac is negative.

Therefore, this quadratic equation two complex solutions.

Please help, Will give brainliest
Talja [164]

Answer:

First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:

a² + b² = c²

30² + b² = 50²

b² = 50² - 30²

b² = 1600

b = 40    Line BL = 40 ft

Since the ladder is 50 feet it is the same length on the other side as well

a² + b² = c²

40² + b² = 50²

b² = 50² - 40²

b² = 900

b = 30        line LM is 30 ft

SO line lm + line bl = 30 + 40 = 70 ft

A is true because ^

B isn't true because as we solved for earlier, BL is 40

C is true because line LM is in fact 30 ft as we solved for

D is not true because as we said earlier BM is 70

E is true because the same ladder was used on both sides of the street
