21

Step-by-step explanation:

7 can go into 21

21

Step-by-step explanation:

Equivalent Fractions with the LCD

8/21=8/21

2/7=6/21

Solution:

Rewriting input as fractions if necessary:

8/21, 2/7

For the denominators (21, 7) the least common multiple (LCM) is 21.

LCM(21, 7)

Therefore, the least common denominator (LCD) is 21.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

8/21=8/21×1/1=8/21

2/7=2/7×3/3=6/21

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
