Hello,
y=x²-10x+7=x²-2*5x+25-25+7=(x-5)²-18
================================
Use the chain rule.
Let u = 25sin²(x), such that dy/dx = dy/du · du/dx


2m3 is. not over3 because. 2is lower than 3
C = 5(F-32)/9 Multiply each side by 9
9C = 5(F-32) Distribute
9C = 5F - 160 Add 160 to each side
9C + 160 = 5F Divide each side by 5
9/5C + 32 = F
