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!

peter buys 12 bunches of bannas for 9.00. use a ratio table to determine how much peter will pay for 8 bunches.
erik [133]

We are given that Peter buys 12 bunches of bananas for 9.00.

We need to determine how much peter will pay for 8 bunches.

Let us set up proportion now.

12 bunches of bananas for 9.00 = 12 : 9

Let us assume Peter will pay for 8 bunches = $x.

Therefore, 8 bunches of bananas for x = 8 : x.

<h3>Setting up proportion:</h3><h3>\frac{12}{9} = \frac{8}{x}</h3>

On cross-multiplying, we get

12x = 9×8

12x = 72.

Dividing both sides by 12, we get

\frac{12x}{12} =\frac{72}{12}

x=6.

<h3>Therefore, Peter will pay $6 for 8 bunches.</h3>
