170 is the correct answer.
Hope this helps.
Answer: (X-12)(x+4)
The middle number is -8 and the last number is -48.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -8
Multiply together to get -48
Can you think of the two numbers?
Try 4 and -12:
4+-12 = -8
4*-12 = -48
Fill in the blanks in
(x+_)(x+_)
with 4 and -12 to get...
(x+4)(x-12)
Answer:
(x+4)(x−12)
Answer:
20 yd²
Step-by-step explanation:
lets do the big one
4 x (6-2) = 4 x 4 = 16 yd²
2 x (4-2) = 2x2 = 4 yd²
16 yd² + 4 yd² = 20 yd²
Another way
Find the area of the figure if it was a rectangle
4 x 6 = 24 yd²
then subtract 2 x 2 = 24 yd² - 4 yd² = 20 yd²
For the given equation ⇒⇒⇒

and the given range 0 ≤ x ≤ π
We should note that the zeros of the denominator will be at
cos x = 0
∴

So, the given equation is undefined at π/2
So, <span>the students error is the division by zero.

See the attached figure which represents the graph of the given equation and we can see it is undefined at π/2
