Answer:
if you have a pic of question send it plz then will give answer
Step-by-step explanation:
2 (-18 - 6) = -48
By order of operations (PEDMAS) the parentheses are calculated first.
The degree of a polynomial is the highest power of x in its expression. Constant (non-zero) polynomials, linear polynomials, quadratics, cubics and quartics are polynomials of degree 0, 1, 2 , 3 and 4 respectively. The function f(x)=0 is also a polynomial, but we say that its degree is 'undefined'.
15x-6+x-3=39
16x-9=39
16x=39+9
16x=48
x=48/16
x=3
