Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
- no solutions in real numbers
To factor, you split the equation so the factors multiply to get the whole equation.
(x-2)(x+2)
Then, interpret the factors.
The zeros can be found at (2,0) and (-2,0).
x=2, x=-2
Answer:
1) 0.024
2) 0.033
3) 4.8
4) 0.16
5) 0.084
6) 0.14
Step-by-step explanation:
1. 3 x 0.008 = 0.024
2. 11 x 0.003 = 0.033
3. 12 x 0.4 = 4.8
4. 4 x 0.04 = 0.16
5. 12 x 0.007 = 0.084
6. 7 x 0.02 = 0.14
