we know that
zeros of any function f(x) are values of x where f(x)=0
Here , f(x) is profit function
so, f(x)=0 when x=15 and x=70
f(x)=0 means profit is 0
and profit is zero means neither gain nor loss
so, woodworker won't either loss or gain when x=15 and x=70
so, option-B.........Answer
Answer:
Step-by-step explanation:
Factorize the denominator
Sum = 4
Product = 3
Factors = 1 , 3 {1*3 = 3 and 1+3 = 4}
x² + 4x + 3 = <u>x² + x</u> + <u>3x + 1*3</u>
= x(x + 1) + 3(x + 1)
= (x + 1)(x + 3)
GCF of the numerator and denominator = (x + 3)
It's **euclid relation** :)
Hope it helps!

Answer:
x = 21
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
Combine like terms. (x + 3x) and (-4 + 100)
x - 4 + 3x + 100 = 180
Subtract 96 on both sides.
4x + 96 = 180
-96 -96
Divide 4 on both sides.
4x = 84
--- -----
4 4
And you get a solution of 21.
x = 21
<u>Check:</u>
Substitute 21 into x.
Add/Subtract from left to right.
21 - 4 + 3(21) + 100 = 180
17 + 63 + 100 = 180
80 + 100 = 180
180 = 180
