The decimal point separates them.
We can l<span>abel the length (l), width (w), and height (h) of the prism and use the </span>formula<span>, SA=2lw+2lh+2hw, because it has '6' faces and to find the </span>surface area put the values in the formula:
SA=2(6)(3)+2(6)(2)+2(2)(3)
SA=36+24+12
SA=72
Answer:
x = 13.6 in
Step-by-step explanation:
The arc x is calculated as
x = circumference of circle × fraction of circle
= 2πr × 
( cancel the 2π on numerator/ denominator )
= 17 × 0.8
= 13.6 in
Answer:
5x - 5
Step-by-step explanation:
Allison: 9x
Adrian: 4x - 5
To find the difference, we subtract Adrian's number of miles, 4x + 5, from Allison's number of miles, 9x.
9x - (4x + 5) =
We think of the negative sign to the left of the parentheses as a -1, and we distribute it by multiplying -1 by 4x and multiplying -1 by 5.
= 9x -1(4x + 5)
= 9x - 4x - 5
Now we combine like terms. The only like terms are 9x and -4x.
= 5x - 5
