Answer:
3.5
Step-by-step explanation:
10.
12*3^2+36 needs to be 540
12*9+36
9+36=45
12*45=540 so
12(3^2+36)
11.
32/2^3-4 needs to be 8
32/(2^3-4)
12.
2.3^2+9*4/2 needs to be 28.58
5.29+9*4/2
(5.29+9)*4/2=28.58
(2.3^2+9)*4/2
Hope this helps :)
Answer:
4n^2-20n+25
Step-by-step explanation:
(-2n+5)^2
=4n^2-20n+25
So 3/4 converted to a decimal is 0.75 .
0.75 X 26 = 19.5
So the answer could be 19.5, but if that’s not available it’s probably because they want it converted back to a fraction.
The answer would be 39/2. Still don’t see that as an answer choice? They might want you to convert that to a mixed number which is 19 1/2 .
Answer: 19.5 , 39/2, or 19 1/2
All are correct
It is a) 6.5 because the formula is lwh/3 and the length and width are both 2 and the height is rt24 because 25-1 is 24 (Pythagorean Theorem) and so when you solve, you get about 6.53 and that rounds to 6.5
