The complete question in the attached figure
we know that
[<span>amount of fabric]=8*[area of lateral triangle side]
area of lateral triangle side=(1/2)*4*5----> 10 ft</span>²
so
[amount of fabric]=8*[10]----> 80 ft²
the answer is80 ft²
Answer:
Your first 2 questions are correctly answered.
I think the answer to the third question is NO.
Step-by-step explanation:
You can see that the sides with 3 and 4 are adjacent, which means they cannot possibly be opposite. For a valid dice, they should be opposite because they add up to 7. Hence this net is not valid.
Answer:
4

Answer:(X+Y)²
X²+Y² would be greater than X²-Y² since addition gives a greater result than subtraction.
X²+Y² would be greater than 2(X+Y); this is because 2(X+Y) = 2X+2Y, which will be less than X²+Y², since X>Y.
(X+Y)² = (X+Y)(X+Y). This can be simplified using the distributive property:
X(X)+X(Y)+Y(X)+Y(Y) = X²+XY+YX+Y² = X²+2XY+Y². This is greater than X²+Y².
