Answer:
$14400
Step-by-step explanation:
Given data
Principal= 6000
Time= 14 years
Rate= 10%
Let us use the simple interest expression to find the final amount
A=P(1+rt)
substitute
A=6000(1+0.1*14)
A=6000(1+1.4)
A=6000*2.4
A=$14400
Hence based on a simple interest model the final amount is $14400
There are many. For example, 32 x 0.5 is 16. You can multiply 4 x 4 to get 16, so it is rational.
Answer:
The answer should be -2x^2+6x
5x/4 plug in any number by x
Answer:
- width: 18 in
- length: 27 in
Step-by-step explanation:
The relations between length (L) and width (W) are ...
W +9 = L
LW = 486
Substituting gives ...
(W+9)W = 486
W^2 +9W -486 = 0 . . . put in standard form
(W +27)(W -18) = 0 . . . . factor
W = 18 . . . . the positive solution
The width of the rectangle is 18 inches; the length is 27 inches.

<em>Comment on factoring</em>
There are a number of ways to solve quadratics. Apart from using a graphing calculator, one of the easiest is factoring. Here, we're looking for factors of -486 that have a sum of 9.
486 = 2 × 3^5, so we might guess that the factors of interest are -2·3² = -18 and 3·3² = 27. These turn out to be correct: -18 +27 = 9; (-18)(27) = -486.
