Answer:
C 9x^2 +15x +36
Step-by-step explanation:
Equilateral triangles have the same angles and the same length sides.
All the sides of the triangle have the length 3x^2+5x+12
The perimeter will be 3s since the sides are the same
P=3s
P =3(3x^2+5x+12)
Distribute
P = 9x^2 +15x +36

Answer:
0.375, 0.125, 0.5
Step-by-step explanation:
given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.
Probability for correct guess = 0.5 remains constant for each of the three questions
X - no of questions is binomial with n =3 and p = 0.5
1) the probability that you guessed right on exactly one of the three questions
= P(X=1)
=
2) the probability that you guessed right on zero of the three questions
=
3) the probability that you guessed right on at least two of the questions
=
The perpendicular slope will be the negative reciprocal,
First, negate the slope
-5/3 becomes 5/3
Flip the numerator and denominator to get the reciprocal
5/3 becomes 3/5
3/5 is the perpendicular slope
