Answer:
The third answer: x+1
Step-by-step explanation:
Remember when writing roots, the signs are backwards. This is because you start with (x-__) and fill in the root.
So for x = -1, it'll be written as (x+1) [aka (x- -1)]
For x = -3, it'll be written as (x+3)
For x = 5, it'll be written as (x-5)
The only answer that is one of these is the the third answer
Answer:
2.94 rads
Step-by-step explanation:
The number of radians that Jose sweeps out equals to the ratio of the chord length, which is the distance he travels in km, to the radius of the circular track, which is 0.9 km
= 2.65 / 0.9 = 2.94 rads
So Jose sweeps an angle of 2.94 radians

Answer:
Area of living room
= 20(x+5)
= 20x +100
Area of dining room= 20x
Total area
= 20x +100 +20x
= 40x +100
Total perimeter (after wall is removed)
= 2(20) + 2( x+x+5)
= 40 + 2(2x+5)
= 40 +4x +10 (expand)
= 4x +50 (simplify)
Step-by-step explanation:
Area of rectangle= length × breadth
