Answer:
35.5 cm
Step-by-step explanation:
The perimeter (P) is calculated as
P = (2 × 6.75 ) + (2 ×
)
= 13.5 + (2 × 11) = 13.5 + 22 = 35.5 cm
Answer:
Step-by-step explanation:
y=x²-2x-1
and y=-3x+5
x²-2x-1=-3x+5
x²+x-6=0
x²+3x-2x-6=0
x(x+3)-2(x+3)=0
(x+3)(x-2)=0
x=-3,2
when x=-3
y=-3×-3+5=9+5=14
when x=2
y=-3×2+5=-6+5=-1
so solutions are (-3,14) and (2,-1)
