Answer:
c = - 7
Step-by-step explanation:
the standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
x² + 4x - 7 = 0 is in standard form
By comparison of the coefficients of the terms, c = - 7
To start, note that the roots of a function have to do with how many times the function passes through the x-axis.
When you look at the graph above, notice that it passes through the x-axis 3 times, at the points (-6,0), (-4,0), and (3,0).
Knowing this, you can conclude that your answer would be choice B.)3
Answer:
... anything less than 2.98??
Step-by-step explanation:
P=2(L+W)
first one
P=2(6+4)
P=2(10)=20
doubled
12 and 8
P=2(12+8)
P=2(20)
P=40
the change is i20
percent change=change/original
change/original=20/20=1=100%
100% change
