Answer: 21 units²
Step-by-step explanation:
Since there is a pair of parallel sides, this figures is a trapezoid. The formula for the area of a trapezoid is , where a and b are the parallel sides and h is the height.
Here, a and b are 5 and 9, while 3 is the height. Let's put all 3 values into the formula.
<em> [Adding in the parentheses]</em>
<em>[Multiplying one-half by 14]</em>
<em /> <em>[Multiplying 7 and 3]</em>
<em />
The area is 21 units².
Answer:
x^22/ 64y^16
Step-by-step explanation:
<h3><u>The variable is equal to 20.</u></h3>
6w + 30 + w = 4w + 90
Subtract 30 from both sides.
6w + w = 4w + 60
Combine like terms.
7w = 4w + 60
Subtract 4w from both sides.
3w = 60
Divide both sides by 3.
w = 20
Answer: (2,8), because the graph of the two equations intersects at this point.
