An equation is shown below:

4(2x – 3) = 1

which of the following correctly shows the first two steps to solve this equation? (1 point)

step 1: 6x – 7 = 1; step 2: 6x = 8
step 1: 6x + 1 = 1; step 2: 6x = 0
step 1: 8x – 12 = 1; step 2: 8x = 13
step 1: 8x – 3 = 1; step 2: 8x = 4

4. find the geometric mean of 4 and 12. 24 8

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
