Simplify the expression by combining like terms: 3x^2 + 12x+11+14x^2+8x+5

Step-by-step explanation:

Like terms have same variables with same exponents

3x² + 12x + 11 +14x² + 8x + 5

= 3x² + 14x² +    12x + 8x   + 11 + 5

= 17x² + 20x + 16

easy math just plug in a and b

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
