Answer/Step-by-step explanation:
The idea to use in solving this problem using the model, is to express the number of shaded boxes in fraction form.
Thus, the blue red shaded boxes has 34 boxes shaded out of 100 boxes. This represents 
. This will give us 0.34.
The other shaded boxes represents 
.
Using the model, we can solve 0.34 + 0.49.
Add both fractions together.

Answer:
Step-by-step explanation:
i cant give you an exact answer but look up the formula for trapezoid and look up the formula for triangle and you will get your answer.
Step-by-step explanation:
it is a multiple of 21.
the highest common factor of 2 numbers is the longest combination of prime factors they have in common.
the prime factors of 21 are simply
3×7
if another number A shares this as the longest combination of prime factors, that means it contains 3×7 itself in its prime factors.
and that means this number A can only be a multiple of 3×7 (= 21), as other prime factors present would be the factor of 21.
-8*21
= -168
