The surface area of a rectangular prism is this:
SA = LW + LH + LH
Here are the changes:
L --> (2/3)L
W --> 4W
H --> H/2
So, the new surface area is:
SA' = (2/3)L (4W) + (2/3)L (H/2) + 4W (H/2)
SA' = (8/3) LW + (1/3) LH + 2 WH
Answer:
19
Step-by-step explanation:
12 2/3 divided by 2/3 = 19
Answer:
1. a=3
2. a=3
3. a=9
Step-by-step explanation:
1. 9/a+9-4=12-56/8+3
We move all terms to the left:
9/a+9-4-(12-56/8+3)=0
Domain of the equation: a=0
a∈R
We add all the numbers together, and all the variables
9/a+9-4-8=0
We add all the numbers together, and all the variables
9/a-3=0
We multiply all the terms by the denominator
-3*a+9=0
We add all the numbers together, and all the variables
-3a+9=0
We move all terms containing a to the left, all other terms to the right
-3a=-9
a=-9/-3
a=+3
Answer:
The result for the equation is .
Step-by-step explanation:
-Solve the equation:
-Subtract from :
-Add both sides by 0.5 :
-Divide both sides by 0.25 :
So, the answer for the equation is .
