Answer:
x=21
Step-by-step explanation:
100+3x+x-4=180
100+4x-4=180
96+4x=180
4x=180-96
4x=84
x=21

Answer:
The location will be at
units.
Step-by-step explanation:
A scuba diver descended at a rate of
units per second.
Now, if 0 represents the surface of the water and distances below the surface are negative, then after
seconds the location of the diver will be given by the followings :
In one second the diver descends by 2.25 units depth.
So, in 12.5 seconds the diver will descend by
units i.e.
units depth.
Therefore, the location will be at
units. (Answer)
The answer is
The side length of the square Kevin cuts is slightly less than the length the instructor required
Answer:
(6y - 1)(6y + 1)
Step-by-step explanation:
To factorize completely, we may adopt the difference of 2 squares approach. The theory states that difference of two square is the product of the difference of the number and the sum of the numbers.
Such that
a² - b² = (a - b) (a + b)
Hence 36y² - 1
= 6²y² - 1²
= (6y)² - 1²
= (6y - 1)(6y + 1)
