Answer:
x = 20
y = 7.2
Step-by-step explanation:
12/x = 9/15
9x = 180
x = 20
12/x= y/12
12/20 = y/12
144 = 20y
y = 7.2
y = 20
Answer:
Step-by-step explanation:
A polynomial is a mathematical expression in sum of powers with one or more variables multiplied by coefficients.
a) 3x² - 5x + 7 is a polynomial
b) x² + 2x - 1 is a polynomial
c) 3x² - 5x + 7 - [x² + 2x -1 ]= 3x² - 5x + 7 - x² - 2x + 1
{add like terms} = 3x² - x² - 5x - 2x +7 +1
= 2x² - 7x + 8
2x² - 7x + 8 is a polynomial
d) Constant term = 8
