Answer:-14
Step-by-step explanation:
/A/= (3 x-1)- (1 x 11)
= -3 -11= -14
F(-7) = 2x + 8,
f(-7) = 2(-7) + 8,
f(-7) = -14 + 8,
f(-7) = -6
Hope this helps you out, I didn't know if there was a plus sign between 2x and 8 but hope this helps you out!
Answer:
9.6km / 9600m
Step-by-step explanation
B= 0.5km
L = 0.7km
perimeter of a rectangle = 2(L+B)
= 2( 0.7 + 0.5)
= 2.4km
wire for one round is 2.4km
wire for 4 rounds = 2.4 x 4
= 9.6km wire is required.
Hence, 9.6km wire is required to fence the rectangular piece of land 4 times.
