Answer:
x = 19, 17
Step-by-step explanation:
(x-18)(x-18)=1
x^2 - 36x + 324=1
x^2 - 36x = -323
x^2 - 36x + 323 = 1
(x-19)(x-17) = 0
x = 19, 17
Answer:
6x
Step-by-step explanation:
Combining like terms is simply representing them as a single term. With algebra, you can perform arithmetic on the coefficient (the 10 and the 4) to simplify the expression, giving you 6x.
Answer:
y°= 51.30°
Step-by-step explanation:
Apply the formula for tangent of an angle
Tan Ф = opposite side length/adjacent side length
Tan y= 10/8
Tan y= 1.25
y° = tan⁻(1.25) = 51.34°
To the nearest tenth y°= 51.30°
Answer:
is this supposed to say 7.7 x 
? if so then it's 770 (you move the decimal over 2 places to the right)
Replace the x values in the equation, then solve:
[(-2)^2+4]/[(-2)^2-2(-2)-48=
(4+4)/4+4-48=
8/8-48=
8/-40=
-1/5
