The height of a triangle is 4 inches. Greater than twice it's base. The area of the triangle is no more than 168 in.². Which any
mestny [16]

Step-by-step explanation:

this problem seeks to test our knowledge on word problems and algebra

<u>Solution</u>

let the base be x, and

the height h = 2x+4

We know that area of a triangle is given as

A= \frac{1}{2} b*h

substituting our given values we have

168= \frac{1}{2} x*(2x+4)\\\\168= \frac{2x^2+4x}{2} \\\\168= x^2+2x\\\\

re-arranging we have

x^2+2x-168=0\\\\

we can now find two factors that will add up to give 2 and multiply to give -168

they are 14 and -12

x^2-14x+12x-168=0\\\\x(x-14)+12(x- 14)=0\\\\x+12=0\\\\x=-12\\\\x-14=0\\\\x=14

The possible base of the triangle is 14 in

and the height is

h= 2x+4\\\\h=2(14)+4\\\\h= 28+4\\\\\h= 32 in

The total cost of a new autombile, including a 4% sales tax on the price of the automobile, is $28,835. how much of the total co
lara [203]

We can write the first part of this problem as: What is 6.5% of $29,990.

"Percent" or "%" means "per 100" or "out of 100". Therefore

6.5 hope this helps (:

%

can be written as

6.5

100

.

When dealing with percentages the word "of" means the product of or to multiply.

Let's call the sales tax amount we are looking for

s

.

We can now write the problem as:

s

=

6.5

100

×

$

29990

s

=

$

194935

100

s

=

$

1949.35

The sales tax on the car is: $1,949.35.

The total price of the car is then:

$

29

,

990.00

+

$

1

,

949.35

=
