A = (1/2)(b1 + b2)(h)
A = (1/2)(8 + 14)(4)
A = (1/2)(22)(4)
A = 44 ft^2
The angle is obviously larger than a right angle because it is bending outwards. This means it is greater than 90°, so ∠2 must be an obtuse angle.
Answer:
2.8 is correct
Step-by-step explanation:
4.0
- 1.2
The 0 becomes 10
10 - 2 = 8
The 4 becomes 3
3 - 1 =2
2.8

Answer: x-3</h3>
Since p(3) = 0, this means x = 3 plugs into p(x) to get 0
We can write p(x) as p(x) = (x-3)q(x) where q(x) is some other polynomial that multiplies with (x-3) to lead to x^3-3x^2-x+3
Let's plug in x = 3 and see what happens
p(x) = (x-3)q(x)
p(3) = (3-3)q(3)
p(3) = 0*q(3)
p(3) = 0
No matter what the result of q(3) was, it doesn't matter because it multiplies with 0 to get 0.
The general rule is: if p(k) = 0, then x-k is a factor of p(x). This is a special case of the remainder theorem.
