Remember that multiplication is to be done before addition or subtraction.  We see that both terms have the factor 0.85:

0.85 × 0.85 +2 × 0.85 ×0.15 × 0.15 =

0.85 * ( 0.85 + 2*0.15*0.15).  

This is equivalent to 0.85 ( 0.85 + 2*0.0225 ) = 0.85 ( 0.895 ).

This last result could be left as is, or evaluated with a calculator:

0.76075

Answer:

A=6\sqrt{5}\ units^2

Step-by-step explanation:

we know that

Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.  

so

A=\sqrt{s(s-a)(s-b)(s-c)}

where

a, b and c are the length sides of triangle

s is the semi-perimeter of triangle

we have

a=9\ units,b=4\ units,c=7\ units

Find the semi-perimeter s  

s=\frac{9+4+7}{2}=10\ units

Find the area of triangle

A=\sqrt{10(10-9)(10-4)(10-7)}

A=\sqrt{10(1)(6)(3)}

A=\sqrt{180}\ units^2

Simplify

A=6\sqrt{5}\ units^2

dalvyx [7]

Answer:

<u>Terrance will need a mortgage loan of US$ 174,250</u>

Step-by-step explanation:

1. Let's review the information given to solve the question.

Value of the house Terrance Jacobs is going to buy = US$ 205,000

Down payment Terrance can afford = 15% of the value of the house

Down payment Terrance can afford = 15% of US$ 205,000

Down payment Terrance can afford = 15% * 205,000

<u>Down payment Terrance can afford = US$ 30,750</u>

2. For finding the amount of the mortgage loan Terrance need for buying the house, we should do this:

Amount of mortgage loan = Value of the house - Down payment

Amount of mortgage loan = 205,000 - 30,750

<u>Amount of mortgage loan = US$ 174,250</u>

<u>Terrance will need a mortgage loan of US$ 174,250</u>
