Expand & simplify 6 ( 4 c + 2 ) − 6 ( 2 c − 2 )

Step-by-step explanation:

The first step, is to distribute. Multiply 6 to 4c and 2. Also multiply -6 to 2c and 2. After the distribution, you'd end up with 24c + 12 - 12c +12.

After this, the second step is to combine like terms. We know that 24c and -12c both have the variable of c. So, 24c - 12c=12c. We also know that 12 and 12 are also alike, so 12 + 12=24.

Now, we are left with the answer of 12c + 24.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
