1.69 is 1.3 to the second power
Answer:
12 cm
Step-by-step explanation:
The formula for the area of a trapezoid is written as:
1/2(b1 + b2)h
h = height = 16 cm
b1 = Length of one parallel side = 9cm
b2 = Length of second parallel side = ?
Area of trapezoid = 168cm²
The formula to find the length of the second parallel side =
b2 = 2A/h - b1
b2 = 2 × 168/16 - 9
b2 = 336/16 - 9
b2 = 21 - 9
b2 = 12cm
Therefore, the length of the second parallel side is 12 cm
Answer:
-5-3i
Step-by-step explanation:
3-8= -5
-5-(-)2i
-5+2i=-3i
400(1.07)=428
28(5)=140
140+400= 540.
$540 is your answer
