Answer:
12m -15
Step-by-step explanation:
Distribute
3(4m-5)
3*4m -3*5
12m -15
Let...
l=length
w=width
Because we know that the perimeter is 90, we can make this equation...
2l+2w=90
Because we know that the length is 5 feet less than 4 times the width, we can make this equation...
l=4w-5
We can solve this system through substitution...
2(4w-5)+2w=90
8w-10+2w=90
10w=100
w=10 ft
l=4(10)-5=35 ft
Answer:
Step-by-step explanation:
5,000 will be i think not sure
6 and 30 camd be simplified with 6
the result will be 1:5
so the question mark is 5
5.291 to 2 d.p I think that is the answer.
