Since the dvd is $7.55 "Less" than the CD you should add.
$14.95+$7.55=$22.5
That's your answer to how much the dvd is.
If you have to subtract it
Write it like this $22.5-$7.55=$14.95
The bottom square portion would be 10 x 10 = 100 square inches.
The area of the triangle would be 1/2 x base x height.
The base is 10 - 6 = 4 inches.
The height is 16 -10 = 6 inches.
Area = 1/2 x 4 x 6 = 12 square inches.
Total area = 100 + 12 = 112 square inches.
Step-by-step explanation:
Blue portion is a rectangle:
Answer:
<h2>∠DBE = 105°</h2>
Step-by-step explanation:
Angles on one side of a straight line always add to 180°.
Therefore we have the equation:
<em>combine like terms</em>
<em>subtract 20 from both sides</em>
<em>divide both sides by 4</em>
∠DBE = 3x - 15. Substitute:
16 + (-9) + 2 = 9 Well sixteen plus negative nine plus two is equaled out to be positive nine.
