Expand (2x - 4)2 using the square of a binomial formula. (x)2 + 2(x)(4) + 42
O (2x)2 + 2(2x)(4) - 42
O(x2 - 2(x)(4) - 42
(2x)2 - 2(2x)(4) + 42

Step-by-step explanation:

We have to expand,

(2x — 4)²

(2x)² + (4)² ― 2(2x × 4)

4x² + 16 ― 2(8x)

4x² + 16 ― 16x

4x² ― 16x + 16

Hence, solved!

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
