Which of the following side lengths can form a triangle?

Margaret [11]

Okay, so my last answer was deleted because I didnt show any work.

According to the rule,

a+b>c

c+b>a

c+a>b

so...

2+3=6...6<7

21+23=44...44+44

12+36=48...48<53

14+17=31...31>30

Since answer D is the only answer that fullfills the rule a+b>c, it is the correct answer

Write in standard form (×+4)(×-5)=4 find the value of a,b,c

Alex17521 [72]

Answer:

$x^{2}$ - x - 24 = 0

a = 1

b = 1

c = -24

Step-by-step explanation:

(x + 4)(x - 5) = 4

x(x - 5) = $x^{2}$ - 5x

4(x - 5) = 4x - 20

$x^{2}$ - 5x + 4x - 20 = 4

$x^{2}$ - x - 20 = 4

$x^{2}$ - x - 20 - 4 = 0

$x^{2}$ - x - 24 = 0

a = 1

b = 1

c = -24
