P=2*(L+l)=46
L+l=46:2
L+l=23
(L+l)^2=529
(L^2+l^2)+2l*L=529
D= V L^2+l^2= 17
L^2+l^2=289
so 289+2l*L=529
2l*L=529-289=240
l*L=240:2
A=120
Answer:
24 feet
Step-by-step explanation:
Length: x
Width: 5x/8
Area = x(5x/8) = 360
x² = 576
x = 24
Answer:
C
Step-by-step explanation:
(x+2)² + (y-3)² = 3²
x² + y² + 4x - 6y + 4 + 9 - 9 = 0
x² + y² + 4x - 6y + 4 = 0

Answer:
(- 2 ; 4) or (-5 ; 1)
Step-by-step explanation:
y = x + 6
y = x² + 8x + 16
x + 6 = x² + 8x + 16
x² + 8x + 16 - x - 6 = 0
x² + 7x + 10 = 0
x² + 5x + 2x + 10 = 0
x(x + 5) + 2(x + 5) = 0
(x + 2)(x + 5) = 0
x + 2 = 0 => x₁ = - 2
x + 5 = 0 => x₂ = - 5
y₁ = - 2 + 6 => y₁ = 4
y₂ = - 5 + 6 => y₂ = 1
