Answer: 2.4×10^5
Step-by-step explanation:
30×8×10^3
First multiply and forget about ×10^3 for now:
30×8 = 240
Then add back the ×10^3:
240×10^3
Then simplify:
2.4×10^5
To check the answer:
30×8×10³=
30×8000= 240000
Then simplify:
240000 = 2.4 ×10⁵
Use the difference of 2 squares (a - b)(a + b) = a^2 - b^2:-
(x - 1/x)(x + 1/x) = x^2 - (1/x)^2
= x^2 - 1/x^2
(x ^2 - 1/x^2)(x^2 + 1 /x^2)
= x^4 - 1/x^4
(x^4 - 1/x^4)(x^4 + 1/x^4)
= x^8 - 1 /x^8 Answer
We can split it up into a net
actually, here is a hack
notice that indented side?
we can take the plane and push it so it makes 4 sides, neat
ok, so we now just have 4 normal sides and 2 L shapes
L shape can be cut into 2 rectangles
5 by 5 and 5 by 10 so total of 75 is the L
2 L's so
2*75=150
the sides
4 of them
they all are 10 by 3
10*3*4=120
toatl is 150+120=270
answer is A
