If two opposite sides of a square are increased by 8 meters and the other sides are decreased by 5 meters, the area of the recta
Alchen [17]

Answer:

21

Step-by-step explanation:

8 * 2 = 16

5 * 2 = 10

68 - 16 = 52 - 10 = 42.

The perimeter of the square is 42.

42 / 4 = 10.5. 10.5 is the length of a side.

10.5 * 2 = 21.

Heres what i needed help with
insens350 [35]
PART A
move 2/3 to the right side so we could find the value of A
(2/3)A = -24
A = -24 ÷ 2/3
A = -24 × 3/2
A = -72/2
A = -36
Point A is -36

PART B
move -0.2 to the other side so we could find the value of B
-(B)/0.2 = 20
-B = 20 × 0.2
-B = 4
B = -4
Point B is -4

PART C
Find the distance between -36 and -4
d = |-36 - (-4)|
d = |-36 + 4|
d = |-32|
d = 32
The distance of the two points is 32

Hitman42 [59]
1 \ kg=1000 \ g \ - \ \$6 \\
400 \ g \ - \ x \\ \\
\frac{1000}{6}=\frac{400}{x} \\

1000x=2400 \\
x=\frac{2400}{1000} \\
x=2.4
