Answer:
x = -2, 1/2
Step-by-step explanation:
Step 1: Isolate everything to 1 side
2x² + 3x - 2 = 0
Step 2: Factor
(2x - 1)(x + 2) = 0
Step 3: Find roots
2x - 1 = 0
2x = 1
x = 1/2
x + 2 = 0
x = -2
The third side measures exactly 15 centimetres (cm).
There are two ways you can do this question, you can one, subtract the 90 from 538 which should give you 448 then you can divide 448 by 16. Your answer should be 28 pies

Answer:
see below
Step-by-step explanation:
Each piece of the graph is a horizontal line extending the length of the domain for that piece. The ≤ symbol means the corresponding line end will have a filled dot. The < symbol means the corresponding line end will have an open dot.
A = A
B = 3A + 18
C = A + 42
The sum of the angles of a triangle equals 180°
A + B + C = 180
(A) + (3A + 18) + (A + 42) = 180
5A + 60 = 180
5A = 120
A = 24
B = 3A + 18 = 3(24) + 18 = 72 + 18 = 90
C = A + 42 = C = 24 + 42 = 66
Answer: A=24, B=90, C=66
