Find the area of the rectangle.
(8x+5) yards
(8x-5) yards

Step-by-step explanation: To find the area, we can use the F.O.I.L. method.

Notice that these two binomials are identical except

that one has a plus and one has a minus.

These types of binomials are called conjugates.

If you're asked to F.O.I.L. two conjugates, you can  

ignore the outer and inner products,

knowing they will cancel each other out.

So the answer to this problem comes from the product

of the first terms and the product of the last terms.

So our answer is 64x² - 25.

step-by-step explanation:

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
