B^2-6b+8 turns into b^2-2b-4b+8 due to the sum product pattern. which then turns into b(b-2) - 4(b-2) and then its (b-4)(b-2)
Answer:
f ( 7 ) = 342
Step-by-step explanation:
Step 1:
f ( x ) = x³ - 1 Function
Step 2:
f ( 7 ) = 7³ - 1 Input x value
Step 3:
f ( 7 ) = 343 - 1 Exponents
Answer:
f ( 7 ) = 342 Subtract

Hello there i hope you are having a good day :) Your question : The cost of 12 oranges and 7 couples is 55.36. Eight oranges and apples cost $3.68. Find the cost of each : Firstly you would do oranges = O Apples = A. Then 12 oranges + 7 apples = 5.36 12o + 7A = 5.36 then you would take away from both sides so -12o Take away -12o = 7o = 5.36 - 12A now you would divide this by 7 so 7 cancels each out so you are left with 5.36/ 7 = 0.76 Then it would equal 0.76 - 12o/7 This would equal the amount of apples to be $0.76 each now for the oranges you would do the same that you work out for the apples.
Hopefully that help ya :)
To solve you insert into proportions, then cross-multiply and simplify.
But first, add 5 and 6 to get the full side length of the bigger triangle
11x = 27.5
x = 2.5Hope this helps!
