Answer:
Zeros are x = 1.5, -2.5
Step-by-step explanation:
Given function is,
F(x) = 4x² + 4x - 15
= 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]
F(x) = 4(x² + 2.5x - 1.5x - 3.75)
= 4[x(x + 2.5) - 1.5(x + 2.5)]
= 4(x - 1.5)(x + 2.5)
For 'x' intercepts,
f(x) = 0
4(x - 1.5)(x + 2.5) = 0
x = 1.5, -2.5
Therefore, zeros of the given function are x = 1.5, -2.5.

Answer:
Area of a triangle =
area of rectangle
Step-by-step explanation:
Given:
Height of triangle = n cm, Base of triangle = m
Length of rectangle = n cm, Width of rectangle = m cm
Area of ΔTRI =
base × height
=
( m ) × (n) ⇒
mn
Area of Rectangle RECT = Length × Width
= m × n ⇒ = mn
Comparing Area of triangle and rectangle.
mn = mn
We can conclude that area of triangle is half of the area of rectangle.
A because they are parallel and equal
