Answer:
11+4x
Step-by-step explanation:
2+3(x+3)+x
Distribute 3 through the parenthesis
2+3x+9+x
Add the numbers
11+3x+x
Collect thw like terms
11+4x
To determine the amount of gold plating necessary for the similar box, you will use the fact that it is 8 times larger in volume to determine how many times larger the area is. This would be what you will multiply $125 by.
Volume is a three dimensional measurement, so the fact that it is 8 times larger tells us each dimension was 2 times larger (2 x 2 x 2=8).
Area is a two dimensional measurement, so the area would have been 2 x 2 or 4 times larger. This means the price would be 4 times as much.
$125 x 4 = $500.
It will cost $500 to gold plate the similar jewelry box.
ANSWER
56.1 square inches.
EXPLANATION
The area of this triangle can be calculated using the formula,
where a=8in.
b=14.2 in.
and C=99° is the included angle.
We plug in these values to obtain,
We round to the nearest tenth to get,
56.1 sq. inch
