Answer: x^2+8x+16
Step-by-step explanation:
Following (a+b)^2=a^2+2ab+b^2,
(x+4)^2=x^2+2(4x)+(4)^2
x^2+8x+16
Answer:
I would love to answer it but I can't find the pie chart.
SOH CAH TOA tells you the sine ratio is
Sin = Opposite/Hypotenuse
sin(x) = 12.5/15
Then the angle x can be found using the inverse function.
x = arcsin(12.5/15) ≈ 56°
The appropriate choice is
b) 56
Answer:
-21x-8
Step-by-step explanation:
(13x-3)+(-34x-5)
(13x-34x)+(-3-5)
-21x+(-8)=
-21x-8
