Answer:
x = 128°
Step-by-step explanation:
123 + 109 + x = 360
x = 360 - (123 + 109)
x = 360 - 232
x = 128°
A^2+b^2=c^2
42^2+b^2=58^2
1764+b^2=3364
b^2=3364-1764
b^2=1600
square root b^2=square root 1600
b=40 inches
Answer:
the third option: x + 2(2x - 4) = 10
Step-by-step explanation:
the question tells you that y = 2x - 4.
so, instead of writing y in the equation, just replace it with 2x - 4.
x - 2y = 10
becomes
x - 2(2x-4) = 10
Answer:
=x(x-1) +3x
= x^2-x+3x
=x^2 +2x
=x(x+2)
