The answer is 16,300. To get the answer, you just move the decimal over 4 places to the right and add your zeros in.
hopefully this helps
Answer:
(1) = (e) 7x. (2) = (b) 7+x. (3) = (d) x-7. (4) = (c) 2x+7
Substitute x for 7.
f(x)=22x+12
f(7)=22(7)+12
Multiply first, then complete addition.
f(7)=154+12
f(7)=166
Ok so 4*5=20
so the area is 20meters
now lets convert 200cm to m
= 200/100=2m
now 20m/2=10
so therefore, the gardener would need 10 bags of grass seeds
