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
The answer is 275 because when you multiply 11 by 25 you get 275
2x-3y=6
3y=2x-6
y=2/3x-2
Slope = 2/3
Therefore B
Answer:
two coordinates would be (3,5) & (9,15)
Step-by-step explanation:
5/3 x 9= 45/3= 15
and written in coordinate form it is (9,15)
5/3 x 3= 15/3= 5
written in coordinate form it is (3.5)
Slope 2/1, y intercept is 6, equation is f(x)=6-2x
