Area is trapezium =
A=1/2h(a+b)
84=1/2(6)(7+b)
84=3(7+b)
84=21+3b
3b=84-21
B=63/3
B= 21 cm
I’m sorry if my answer turned out to be wrong but I tried my best so best of luck !!
Answer:
zero
Step-by-step explanation:
because when u equate both equation ,
-2x-5= -2x+7
or, -2x+2x=7+5
or, 0=12
which is invalid so it has no solution
-x^5 - x^2+ 9
Here’s your answer
Answer:
3 3/11
Step-by-step explanation:
The best way to divide fractions is to not divide them at all.
Convert both mixed numbers into improper fractions.
4 times 2 is 8
8 + 1 is 9
I have 9/2 halves. Don't forget to put the negative back in.
1 times 8 is 8
8 + 3 is 11
I have 11/8 eighths. Dont forget to put the negative back in.
You will end up with
-9/2 ÷ -11/8
Flip the second fraction and change the division sign to a multiply sign
-9/2 × 8/-11
Multiply the numerators together and the denominators together
-9 x 8 and 2 x -11
-72 / -22
Dividing a negative by a negative will give us a positive
72 / 22
Simplify by dividing the top and bottom by 2
36/11
We cannot simplify further. You can answer like this or convert back into a mixed number.
There are 3 sets of 11 in 36, with 3 left over
3 3/11
= 12.96
