Answer: the answer is 42 degress
Step-by-step explanation: A strait line would equal 180 degress so subtract the angle you know witch is 138 degress to get 42 degress
1. 3b + 69 = 45
2. 3b = 45 - 69
3. 3b = -24
4. 3b/3 = -24
5. b = -24/3
6. b = -8
answer is b = -8
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>
