Evaluate the expression 21 + 2w for / = 5.7 and w = 6.2. Enter your answer in the box.
6.2

23.8

Step-by-step explanation:

2l+2w for l=5.7 and w=6.2

2*5.7+2*6.2 first multiply

11.4+12.4 then add

23.8

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
