Answer: a = -2/3
Step-by-step explanation:
Let's start by multiplying both sides by 
to simplify:
Looking only at the exponents, it seems like 
, so 
.
It is 3 because if you count it 5-11 that’s 6 but you have to divide it by 2 sense there is 2 so that answer is 4
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
Answer:
What you put is correct
Step-by-step explanation:
Because it is -3 and its pointing to the right so the arrow would be like that.
• Climate change increases local plant species richness, at least temporarily
• Empirical and modeled data suggest an increase of ∼5% per decade in cool regions
• Climatic perturbation is identified as a process driving biodiversity accrual
• Uneven global coverage of field data could be obscuring other climatic effects
