Answer:
The volume of the figure is 51.66 in3
Step-by-step explanation:
sol;
volume of prism=area of trangular base * length of prism
=1/2*b*p*7.2
=1/2*4.1*3.5*7.2
=51.66 in3
Answer: x=1+1/3
Step-by-step explanation: -(3x-12)=9x-4
We move all terms to the left:
-(3x-12)-(9x-4)=0
We get rid of parentheses
-3x-9x+12+4=0
We add all the numbers together, and all the variables
-12x+16=0
We move all terms containing x to the left, all other terms to the right
-12x=-16
x=-16/-12
x=1+1/3
1/3b+1/3c is the expression assuming bikes are counted as vehicles
Answer:
The answer to the question is 10a√2a(b + 2)
Step-by-step explanation:
To know the student's error, let us calculate the perimeter from the the start.
Dimension of the rectangle is given below:
√(50a³b²) and √(200a³)
Perimeter of a rectangle = 2(L + B) = 2L + 2B
2√(50a³b²) + 2√(200a³)
2 x 5ab√2a + 2 x 10a√2a
10ab√2a + 20a√2a
Factorise
10a√2a (b + 2)
Therefore, the student made an error by adding 10ab√2a and 20a√2a together.
Note: we can not add 10ab√2a and 20a√2a together since b is missing in one of the expression.
Therefore, the answer to the question is 10a√2a(b + 2).
