Answer:
The answer to the geometry is 45
Answer:
Step-by-step explanation:
The two x intercepts are
x - 7 = 0
x = 7
x + 3= 0
x = - 3
The y intercept is just - 7 * 3 = - 21
To prove this more formally
f(x) = (x - 7)(x + 3)
f(x) = x^2 - 7x + 3x - 21
f(x) = x^2 - 4x - 21
Step-by-step explanation:
3c³ - 7d
= 3(-4)³ - 7(6)
= 3(-64) - 42
= -234.
