The following steps are used to rewrite the polynomial expression, 3(x + 4y + 5(2x - y).
&
step 1: (3x + 12y) + (10x - 5y)
step 2: (3x + 12y) + (-5y + 10x)
step 3: 3x + (12y-5y) + 10x
step 4: 3x + 10x + (12y - 5y)
step 5: 13x + 7y
identify the property used in each of the steps:

The polynomial function of least degree with a leading coefficient of 1 is: f(x) = x3 + ax2 + bx + c

The formula for the lateral area of a right cone is la = rs, where r is the radius of the base and s is the slant height of the cone.which are equivalent equations?

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
