Answers

Hi there this is a puzzle question. So lets get to the answer. If 1+4=5 then we take 1+(4*1)=5. 2+5=12 so lets take 2+(5*2)=12. 3+6=21 so lets take 3+(6*3)=21. After all of this you should probably know now that I multiplied the first number with the second number then added both of the numbers. So, 8+11=8+(11*8)=8+88=96. Therefore, the answer is 96.

What's the length of side b in the figure below? I posted a picture so you can view the actual problem. Please help.

Answers

the answer would be letter c because you have to use orders of operations io on aka A^2+B^2=C^2
how to set it up woulf look like this: a^2= 7^2
B^2=?, and C^2=13^2
in other words a=7squared
B=?
and C=13 squared
so the problem would end up like this:.7*7+B*2=13*13
49+B*2=169
so now you subtract 169 from 49 and that equals B*2=√120

we know that

in the right triangle of the figure

Applying the Pythagorean Theorem

$13^(2) =b^(2) +7^(2) \n b^(2) =13^(2)-7^(2)\n b^(2)=120\n b=√(120) \ cm$

therefore

the answer is the option

C) $b=√(120) \ centimeters$
