Answer: B. 2=3x+10x^2
Step-by-step explanation:
The expression means the quadratic function equation.
B = 10x^2 + 3x -2 = 0
the equation is [-b ±√(b^2 -4ac)]/2a
b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
The weight is 62 and a half lb per cubic feet.
Answer:
C.
Step-by-step explanation:
In total, Sophie needs $230.40.
Let's form an equation. 230.40 = 12.80x
You'll need to divide both sides by 12.80 to get the variable, x, by itself.
18 = x
Therefore the answer is C.
U have to measure what ever your measuring example
say your measuring a square measure the sides like this --> |_| <---
these sides
enjoy
C I think if it’s wrong I’m sorry
