It's just saying that you need to find the volume and surface area and then write them in the designated area, which will be on the side or the bottom.
After doing this for all of them, you have to find two matching numbers and put them together on the same side.
For example:
When you got 722, you can just find another square that might say 722 on square area or volume, then just put the numbers together on the same side.
I don't know if this helped but I hope it did!
Answer:
Perimeter = 16x + 16
Area = 40x + 15
Step-by-step explanation:
Perimeter = the sum of all the side lengths
Perimeter = 2(8x+3) + 2(5) = 16x + 6 + 10 = 16x + 16
Area = product of base times height
Area = (8x+3)*5 = 40x + 15

Second half: 12 miles per hour for 20 miles. Time taken:
In total, he traveled 60 (30+30) miles in 4 hours (1.5+2.5), for an average speed of
Answer:
7
Step-by-step explanation:
Quadratic Equation: 3x² - 24x + 72
The form we are to convert the equation to:
3x² - 24x + 72
a(x + b)² + 72
3(x² - 8x + 24)
Step 1
Make the Quadratic equation (x² - 8x) in the bracket factorisable using completing the square method
3( x² - 8x +(- 8/2)²) + 24
3( x² - 8x + 16 = -24 + 16
3( x² - 8x + 16 + 8 = 0)
3( x² - 8x + 16) + 8
3( x² - 4x + 4x + 16) + 8
3( x(x - 4) -4(x - 4) + 8
3((x - 4)(x - 4) )+ 8
3( (x - 4)² + 8
Using this form
a(x + b)² + c
a = 3
b = -4
c = 8
We were asked to add up constants a, b, c
Therefore,
3 +(-4) + 8
= 7
Answer:
(10x+4x^2+13)
Step-by-step explanation: 10 and 3 do not have a variable therefore they go together (both being positive you add). 2x, 2x, and 6x have the same variable, being positive you add. 4x^2 is the only number with the x^2 variable and stays by itself due to no others.
