Answer:

Step-by-step explanation:

Let width = x

Length = 7 + x

Perimeter = 42 yards

2*(length + width) = 42

2* ( 7 + x + x) = 42

7 + 2x = 42/2

7 + 2x = 21

2x = 21 - 7

2x = 14

x = 14/2

x = 7

Width = 7 yards

Length = 7 + 7 = 14 yards

Alexander is a high school basketball player. In a particular game, he made some two point shots and some three point shots. Ale
andrezito [222]

Answer:

2 three points shots and 4 two points shots

Step-by-step explanation:

Let x be the number of three points shots.

Alexander  made twice as many two points shots as three points shots, so the number of two points shots is 2x.

Amount earned in three points shots =3\cdot x

Amount earned in two points shots =2\cdot (2x)=4x

Total score =3x+4x=7x

Alexander scores a total of 14 points, then

7x=14\\ \\x=2\\ \\2x=2\cdot 2=4
