Can you please solve this?

1) d

2) d

3) yes

4) no

5) B

Step-by-step explanation:

1) Angle opposite the longest side is the greatest.

AB < BC < AC

Therefore,

Angle C < Angle A < Angle B

2) angle A = 180 - 55 - 45 = 80

Angle B < Angle C < Angle A

AC < AB < BC

3) 9, 12, 15

To form a triangle;

longest side < sum of two shorter

sides

15 < 9 + 12

15 < 21 is a true statement

4) 4, sqrt(12), 7

To form a triangle;

longest side < sum of two shorter

sides

7 < 4 + sqrt(12)

7 < 7.46 is a false statement

5) To form a triangle;

longest side < sum of two shorter

sides

This is satisfied only in B

19 < 9 + 11

19 < 20 is a true statement

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
