Answer: the equation is
4x^2 + 4x - 12
Step-by-step explanation:
A quadratic equation is an equation in which the highest power of the unknown is 2.
The general form of a quadratic equation is expressed as
ax^2 + bx + c
Where
a is the leading coefficient
c is a constant
Assuming we want to write the quadratic equation in x, from the information given, the roots which are given are -2 and 1 and the leading coefficient is 4.
Therefore, the linear factors of the quadratic equation will be (x+2) and (x-1)
the equation becomes
(x+2)(x-1)
= x^2 - x +2x - 3
= x^2 + x - 3
Given a leading coefficient of 4, we will multiply the quadratic expression by 4. It becomes
4(x^2 + x - 3)
= 4x^2 + 4x - 12
Answer:
x = 15
Step-by-step explanation:
x/3/9 = 5/9
x : 3 : 9 = 5/9
x×1/3×1/9 = 5/9
x/27 = 5/9
x = 5×27/9
x = 5×3
x = 15
8 out of 18 games. That 8/18 simplify to 4/9 ?
There are total 17bills of $20 dollars and 6 for $10 bills.
We get the answer of $20 bills by dividing 340 and 20 then we get 17 then subtract the value from total bills than you get 6 bills for $10 dollars
