Answer:
2223
Step-by-step explanation:
We need to find the value of 2021-2223+2425.
Firstly subtract 2223 from 2021.
2021-2223 = -202
Now add -202 and 2425. So,
2425 +(-202) = 2223
So, the value of 2021-2223+2425 is 2223. Hence, this is the required solution.
Answer:
x = - 6
Step-by-step explanation:
Given
= 3
Multiply both sides by 5 to clear the fraction
9 - x = 15 ( subtract 9 from both sides )
- x = 6 ( multiply both sides by - 1 )
x = - 6
First expand the brackets by multiply everything in them by 2
2(3x-1)=
6x-2
then add the 4 and the 9 to -2 and you get
6x+11 so therefore its a
Area of trapezium=384 square cm
Ratio of parallel sides=
Distance between parallel sides=h=12 cm
