Answer:
1380 in²
Step-by-step explanation:
The lateral surface is the sum of the areas of all the sides, or 'faces'.
The bases (the top and bottom) are <u>not </u>included.
This is a prism with triangles for bases (at each end). The sides are rectangles.
Add up the areas of the rectangles.
300 + 480 + 600 = 1380
Answer:
B. y - 2x = 5
Step-by-step explanation:
Add 2x to both sides, and the equation becomes, y = 2x + 5, as demonstrated from the graph.
Answer:
2n³ + 4
Step-by-step explanation:
Take off the parentheses (brackets) because there is nothing to multiply with it :
5 + 5n³ - 1 - 3n³
Now arrange the equation :
5n³ - 3n³ + 5 - 1
Subtract all the same variables :
5n³ - 3n³ = 2n³
5 - 1 = 4
Now arrange the equation again :
2n³ + 4
To find this, first we subtract the extra 3 feet from the original 27 feet.
27-3=24
Then, we divide the left over length by three. This will provide us with the length for the shorter piece.
24/3=8
The shorter piece will be 8 feet long.
Now, we double that to find the longer piece without the additional 3 feet.
8x2=16
And we add those two (8 and 16) together to make sure it is equal to the 24 we divided into 3 earlier.
16+8=24
Now all that's left is to add the extra 3 feet to the 16 feet.
16+3=19
And add that to the 8 feet, to check to make sure the lengths add up to our original 27 feet.
19+8=27
Therefore, the two pieces are the following lengths:
Shorter piece: 8 feet
Longer piece: 19 feet
