Answer: 6.4cm
Step-by-step explanation:
The area of a trapezoid is given as:
= 1/2(a + b)h
We then slot the given values into the formula. This will be:
1/2(15.8 + b) × 7.3 = 81.03.
7.3(15.8 + b)= 81.03 × 2
7.3(15.8 + b) = 162.06
115.34 + 7.3b = 162.06
7.3b = 162.06 - 115.34
7.3b = 46.72
b = 46.72/7.3
b = 6.4
Therefore, the answer is 6.4cm.
The correct answers are :
y=-1/2x+5 is parallel.
-2x+y=-4 is perpendicular.
-x+2y=2 is neither.
x+2y=2 is parallel.
<h3>What are parallel lines and perpendicular lines ?</h3>
It is argued that two non-vertical lines in the same plane that have the same slope are parallel.
In terms of geometry, parallel lines are two separate lines that never cross each other and are located in the same plane. They may be vertical or horizontal. Examples of parallel lines can be found all around us on railroad tracks, in lines of notebooks, and at zebra crossings in daily life. It is impossible for two parallel lines to cross. Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane.
Perpendicular lines are two different lines that cross at a right angle of 90 degrees.

Step-by-step explanation:
she has 17 slik roses already, and 6 friends give her 3 silk roses each, so that's 6 times 3, which makes 18, and 17 plus 18 is 35, so she has 35 silk roses in all.
