Find the wronskian of y_1 = 2x + 3, y_2 = x^2 + 3x, and y_3 = x^2 - 1. use the result to determine if the three functions are linearly independent on (- infinity, infinity). w [2x + 3, x^2 + 3x, x^2 - 1] = are the functions linearly independent on (- infinity, infinity)?

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

i dont know sorry

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
