X cannot equal +2, and can't be -1. If you factor it, then you notice you get 2(x+2)(x-2). If you use either one for the x, one will be zero and the won't, and vise-versa.
Answer:
y = 5
Step-by-step explanation:
if y = 5 then
(√10-1) -1 = 2
3 - 1 = 2
true
Answer:
A
Step-by-step explanation:
equation of the line graphed
(y-4)/(2-4) = (x+6)/(0+6)
(y-4)/(-2) = (x+6)/6
y-4 = (x+6)/-3
y = (x+6)/-3 +4
y = (x+6-12)/-3
y = -1/3x + 2
so the answer is A
r + 4(r - 3)
<em><u>We'll use the distributive property to simplify this.</u></em>
r^2 - 3r + 4r - 12
<u><em>Combine like terms</em></u>
r^2 + r - 12 is the simplified form.
Answer:
<em>AB = 7.35 cm</em>
Step-by-step explanation:
From the attachment,
In ΔDEF,
DF = GH-(GD+FH) = 6 - (2+3) = 1 cm
DE = 2+3 = 5 cm (sum of two radius)
Applying Pythagoras theorem,
In ΔCDI,
DI = GH-(GD+IH) = 6 - (2+1.5) = 2.5 cm
CD = 2+1.5 = 3.5 cm (sum of two radius)
Applying Pythagoras theorem,
AB = EF + CI =
