Factor x2 – 4x – 5 = 0.<br><br> WITH ALL STEPS.

Troyanec [42]

x²-4x-5=0

The given equation is quadratic

So we can perform prime factorisation of it.

factors of -5, that add up to give -4 are -5 and 1

therefore replacing -4x by -5x+x

x²-5x+x-5=0

performing factoring by grouping,

(x²-5x)+(x-5)=0

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

(x+1)(x-5)=0

x+1=0 and x-5=0

Answer is x=-1 and x=5

Answer:

C. 28.6 $units^2$ , 0.28

Step-by-step explanation:

<em><u>To find the white portion's area, you add 44 and 47, then multiply it by π</u></em> $r^2$ :

44 + 47 = 91

$\frac{91}{360}$ (3.14) $(6)^2$

A = 28.574 → A = 28.6

<em><u>There are 7 parts of the circle, and 2 of them are white. So divide 2 by 7:</u></em>

2 ÷ 7 = 0.28
