-10x-1 = 11 -9x
+10x +10x
-1 = 11 + x
-11 -11
-12 = x
x= -12

(x^2 +6)(x^2 - 6)
(x^2 + 6)(x + sqrt (6))(x - sqrt (6))
Answer:
Step-by-step explanation:
you know the total angle is 180° from A to D
and you know that ∠BEC is 90°
also you are told that ∠CED is 18°
and that ∠AEB is 4x°
so just put that all together
180=90 + 18 +4x
now solve for X
180-90-18=4x
72=4x
18 = x
so now you know X
now solve ∠AEB
4(18) = 72°
∠AEB= 72°

4y + 3y = 7y
The answer is 7y. Because of the arithmetic rules, bracket should be taken first, then multiplication.
B = bracket
o = of
D = division
M = multiplication
A = addition
S = subtraction
12000 > 3000+25x Or you can write it out as (12000-3000)/25=x
