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 answer is 81x^8 because of the exponent
Multiplication...?? Because if u add a times sign between 4x and -4 then u get 4x
Answer:
10.5
Step-by-step explanation:
42/4 can be reduced by dividing numerator and denominator by 2: 21/2.
This is an improper fraction. One way to obtain the equivalent mixed number would be to multiply numerator and denominator of 21/2 by 5, obtaining 105/10, which reuces to 10.5.
We could also divide 42 by 4 in the usual way, obtaining 10.5.
