The answer is A = P²/16
The perimeter P of a square is sum of its sides s: P = s + s + s + s = 4s
The area A of a square with side s is: A = s * s = s²
Step 1: Solve s from the formula for the perimeter.
Step 2: substitute s from the formula for the perimeter into the formula for the area.
Step 1:
P = 4s
s = P/4
Step 2:
A = s²
s = P/4
A = (P/4)²
A = P²/4²
A = P²/16

Answer:
Step-by-step explanation:
If we let x represent one of the numbers, then you want ...
x(58 -x) = 201.25
x² -58x +201.25 = 0 . . . . . put in standard form
(x² -58x +29²) +201.25 -29² = 0 . . . . complete the square
(x -29)² -639.75 = 0
x -29 = ±√639.75 . . . . . add 639.75 and take the square root
x = 29 ±√639.75 . . . . . . add 29
The two numbers of interest are ...
29 +√639.75 ≈ 54.2933
29 -√639.75 ≈ 3.7067
3-4x+5=16-4x =>>kick 1. -4x to right side =>>
8=16-4x+4x=>> 8=16 that means question is wrong lol
Question should be 3+4x+5=2(8-2x) or 3-4x+5=2(8+2x)
Then the answer will be 8x=8 =>> x=1 :)
Answer:
aₙ = 7n +29
Step-by-step explanation:
22 ; 15 ; 8; 1;........aₙ
aₙ = -7n +29
Perimeter r / perimeter s = side r/ side s
Perimeter r = 72 cm
Perimeter s = 36 cm
Side r = ???
Side s = 6 cm
72/36 = side_r/ 6 Cross multiply
72 * 6 = 36 * side_r
432 = 36 side_r Divide by 36
432 / 36 = side_r
12 = side_r
