Answer:
32cm and 28cm
Step-by-step explanation:
Area of a trapezium=0.5 ( sum of parallel sides ) × height
600=0.5( 4+a+a)×20
where a is the length of the shorter side
600÷0.5=(4+2a)×20
1200=(4+2a)×20
1200÷20=4+2a
60=4+2a
60-4=2a
56=2a
56÷2=a
28=a.
since the longer side is 4 cm more than th shorter side , 28 +4=32
X=30 400+50 equals 450 so 450 divided by 15 is 30 reverse the operation
The resultant force would be 88.88 N at an angle of 43 degrees from the 100 N force.
Answer: 20x-6 = 34
Step-by-step explanation:
Given: The length of rectangle is represented by 8x - 3.
The width of the rectangle is represented by 2x.
The perimeter is 34 inches.
Perimeter of rectangle = 2 (length + width)
Perimeter of rectangle = 2 (8x-3+2x)
Perimeter of rectangle = 2 (10x-3)
Perimeter of rectangle = 20x-6
Thus , the required equation that represent the perimeter: 20x-6 = 34
