Answer: The answer is F.
Step-by-step explanation:
1.) The first equation represents how the spiral notebook has 30 more pages than the the memo book, and how subtracting the memo book's pages would result with 30.
2.) The second equation represents how the total number of pages in 3 spiral notebooks plus 5 memo books would result in 810 total pages.

<span> iscoseles triangle
</span>
3x - 5 = 19 - x
4x = 24
x =6
3x - 5 = 3(6) -5 = 13
2x = 2(6) = 12
perimeter of <span> iscoseles triangle
P = 2a + b
P = 2(13) + 12
P = 26 + 12
P = 38
answer
Perimeter = 38 cm</span>
Answer:
5 m
Step-by-step explanation:
The volume (V) of a square based pyramid is
V = Ah ( A is the area of base and h the height ), thus
A × 12 = 100, that is
4A = 100 ( divide both sides by 4 )
A = 25
Hence s² = 25 ← s is the side of square base
Take the square root of both sides
s = = 5
Answer:
A
Step-by-step explanation:
surface area = length x width x depth
so 5x5x7=175.
