Answer:
18
Step-by-step explanation:
1/2bh
9 x 4 = 36
36/2 = 18
area = 18
The awnser is 729 Bc 81 times 9 equals 729
Yes. It is equivalent to 3. Combine like terms
The answer to this question would be: 6
In this question, you are asked to estimate 90/7 divided by (1 + 3/4). You can convert the 1 3/4 into :
1 +3/4=
4/4 + 3/4= 7/4
Then, the calculation would be:
(90/7) / (7/4)= (90*4)/ (7*7)= 7.347
The distance from 7.347 to 6 would be -1.347. It was much shorter than the distance to 12 which is 4.7. The closest answer would be 6
