Answer: 53
Step-by-step explanation:
The original square had a dimension of x and x was reduced by 2 which means x-2 and 3 was added so the formula will be x-2+3=54 and to work that out you have to do it backwards.
54-3=51
51+2=53
So the original dimension was 53inches
Answer:
864 ft^2
Step-by-step explanation:
Surface area equation is the same as the one used in the other problem; S=(1/2)lP + B
one side is 20 x 14 = 280
another side is 12x14 = 168
another side is 16x14 = 224
the triangle bases are A=(1/2)bh
(1/2)12 x 16 = 96
2(96) = 192
Add all sides together 192 + 224 + 280 + 168 = 864
Answer:
1
Step-by-step explanation:
3+4.55=8.55
8.55-4=4.75
4.75 divided by 4.75 is 1
Answer:
