Answer:
2
Step-by-step explanation:
Hi there,
In order to solve this expression, you need to substitute x for 1.
You will end up with this expression:
3() - 2(1) + 1
Now, simplify the expression.
⇒ 3 - 2 + 1
⇒ 1 + 1
⇒ 2
Therefore, the answer when we evaluate the polynomial for x = 1 is 2.

Step-by-step explanation:
A segment that subtends an arc of θ in a circle of radius r has an area given by ...
A = (1/2)(θ -sin(θ))r² . . . . . where θ is in radians
In your figure, the radius is r = √2 and the angle is 90°, so θ = π/2. Then the area is ...
A = (1/2)(π/2 -sin(π/2))·(√2 units)²
A = (π/2 -1) units²
Answer:
12.35
Step-by-step explanation:
C. Karla says that to solve the equation you first subtract 15 and then divide by 10.
Karla is given the equation 10x + 15 = 20 to solve. She says the solution is 1/2
10x + 15 = 20
10x = 20 - 15 (subtract 5)
10x = 5 (divide by 10)
x = 5/10 = 1/2
