1) Answer is A (True). 5.7 can be written as fraction in which both numbers are whole finite numbers.
2) Answer is True. Explanation is same as for the previous question.
3) √24 is between 4 and 5. √16=4 and √25 is 5, therefore answer is D)
4) Answer is √136. 11²=121 and 12²=144 and the question doesn't include equal scenario which would look like "more or equal than 11 but less or equal than 12".
Answer:
x =-4
Step-by-step explanation:
4x+9 = -2x-15
Add 2x to each side
4x+2x +9 = -2x+2x-15
6x+9 = -15
Subtract 9 from each side
6x +9-9=-15-9
6x = -24
Divide each side by 6
6x/6 = -24/6
x = -4
Answer:
Y=(x+4)*2-3
=x*2+8x+16-3
=x*2+8x+13
So the standard form is B

Answer:
a=3.33m/s^2
Step-by-step explanation:
F=ma
a=F/m
To find Force you have to subtract the gravitational force by the air force
F=600-400
F=200N
m=60kg
Plug in the values:
a=200N/60kg
a=3.33m/s^2
