8×6= 48
4×6=24, 24+24=48
or
(4×6)+(4×6)=2×4×6=8×6
Answer:
The strategies (2), (3) and (5) can be applied.
Step-by-step explanation:
In this case we need to compute the product of 629 × 100.
The product can be found in the following ways:
- multiplying (600 + 20 + 9) x 100

- putting 2 zeros on the end of 629

- multiplying (6,000 + 200 +90) x 10

Thus, the strategies (2), (3) and (5) can be applied.
Answer:
The answer is B
Step-by-step explanation:
on the left picture 5 * 5 = 25 sq ft
on the right picture, 5 * 2 - 10 sq ft
So the answer is B
(2n/6n+4)(3n+2/3n-2)
=2n(3n+2)/(6n+4)(3n-2)
=(6n^2 + 4n)/(18n^2 - 12n + 12n -8)
=(6n^2 + 4n)/(18n^2 - 8)
=2(3n^2 + 2n)/2(9n^2 - 4)
=(3n^2 + 2n)/(9n^2 - 4)
=n(3n+ 2)/(3^2 × n^2 - 2^2)
=n(3n+ 2)/(3n-2)(3n+2)
=n/(3n-2)
Answer:The numerator of the simplified expressions is n.
