124=100+20+4, 17=10+7
124*17=(100+20+4)(10+7)=1000+200+40+700+140+28=2108
-10y^2 + (-3y^2) - 4y^2 - (-6y^2) =
-10y^2 - 3y^2 - 4y^2 + 6y^2 =
-17y^2 + 6y^2 =
- 11y^2
Answer:
4z - 15
4(3) - 15
12 - 15
= -3
High school math? really?
B!
the golden ratio is where the long side can be split into two pieces and both can still be longer than the short side of the rectangle
A. 34x2=68 which is higher than 55 so it couldn’t split into two bigger halves
B. 20x2=40 which is smaller than 45 so it could split into two bigger halves (this one does fit the golden ratio btw)
C. 18x2=36 which is bigger than 34 and couldn’t split into two larger halves
