First, find the lowest common multiple of 5 and 8 and it is 40.
So
-32/40 - 35/40
= -67/40
Answer:
x . 1 . 3 . 5 . 7 . 9
y . 6 . 18 . 30 . 42 . 54
Step-by-step explanation:
X-values are the odd numbers
Y-values are the corresponding x-values multiplied by 6
We know that
[surface area of the pyramid]=area of the base+4*[area of one lateral triangle]
area of the base=14*14------> 196 cm²
area of one lateral triangle=b*h/2
b is the length side of the square
b=14 cm
h is the slant height
h=15 cm
area of one lateral triangle=14*15/2-----> 105 cm²
[surface area of the pyramid]=196 cm²+4*[105 cm²]-----> 616 cm²
the answer is
616 cm²
