the length of a rectangular garden is 3 m greater than the width. The area of the garden is 70m squared. find the dimensions of
Lerok [7]
A = l x w

so you know that the length is 3m longer than the width, so you could use a formula to represent that

w = l + 3

you then substitute the second equation into the first to solve for l

70 = l x (l +3)
70 = l^2 + 3l

you could then rearrange the formula and solve for l using the quadratic formula 

0 = l^2 + 3l - 70

l = -3 +- (square root (3)^2 - 4(1)(70)) / 2(1)
l = -3 +- (square root 9 + 280) / 2
l = -3 +- (square root 289) / 2
l = -3 +- 17 / 2

then you solve for the two seperate roots

l = -3 + 17 /2
l = 14 / 2
l = 7

or 

l = -3 - 17 / 2
l = -20 / 2
l = -10

since a length cannot be negative, this root is not viable. therefore l = 7

to solve for w you would use

w = l + 3
w = 7 + 3
w = 10 

hope this helps! if you did not understand a step or concept please let me know!

Three friends each have some ribbon. Carl has 54 inches of ribbon,Tino has 13.5 feet of ribbon, and Baxter has 3.5 yards of ribb
deff fn [24]

Answer:

  342 inches, or 28.5 feet, or 9.5 yards

Step-by-step explanation:

It is perhaps easiest to start with all the dimensions in inches.

  13.5 ft = (13.5 ft)(12 in/ft) = 162 in

  3.5 yd = (3.5 yd)(36 in/yd) = 126 in

Then the total of the lengths of ribbon is ...

  54 in + 162 in + 126 in = 342 in

Converting to feet, we get ...

  (342 in)/(12 in/ft) = 28.5 ft

And converting to yards, we get ...

  (342 in)/(36 in/yd) = 9.5 yd

The total length of ribbon is 342 inches, or 28.5 feet, or 9.5 yards.
