The width of a rectangle is the length minus 6 units. The area of the rectangle is 27 units. The area of the rectangle is 27 units. What is the length, in units, of the rectangle?

The length is 9 units.

Step-by-step explanation:

x will be our length so we get:

x*(x-6)=27

You can just try the factors of 27 as x.

Let's guess x is 9

9*(9-6)=27

9*3=27

Which is true, so the length must be 9 and the width must be 6.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
