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:
Total tape used by marge is 6 inches .
Step-by-step explanation:
As given
marge cut 16 pieces of tape for mounting pictures on poster board.
Total tape marge uses = Number of pieces × Each piece length
Total tape marge uses = 2 × 3
= 6 inches
Therefore the total tape used by marge is 6 inches .
The y-intercept is (0, 7) the x-intercept is (-3, 0)
Your answer is B
