There are no zeroes for an expression, only for equations.
Assuming equation to be
<span>−7x^2 − 91x − 280=0
-7(x^2+13x+40)=0
-7(x+8)(x+5)=0
by the zero product properties,
x+8=0 => x=-8
or
x+5=0 => x=-5</span>
The coefficient is the number next to the letter.
Although the x squared term has a coefficient of 1, it is not listed in the answer choices. However, the coefficient of the middle term 6x is listed.
Answer: 6
Answer: b
Step-by-step explanation:
Answer:
V = 272.3 cube units
The surface area is 418.34 square units
This looks like an incomplete answer to me...
I cannot see any diagram or window or opening, or any lines that indicate they are line AC or BD.
