Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
2nd question answer is option 3
Answer:
The final answer is 11.9
Step-by-step explanation:
14 x 6 = 84
84/5 = 16.8
16.8 - 4.9 = 11.9

Answer:
Shaquille O'Neal's height= 2,160,000,000 nm
= 2.16 × 10^9 nm
Completed question;
The basketball player Shaquille O'Neal is 7 feet 1 inch tall, which is equivalent to 216 centimeters a nanometer (nm) is a unit of measurement that is one-billionth of a meter, convert his height to nanometers.
Step-by-step explanation:
Given;
Shaquille O'Neal's height= 216cm = 216 × 1/100 m = 2.16m
Since, a nanometer (nm) is a unit of measurement that is one-billionth of a meter.
1 m = 1 billion nanometers
So,
2.16m = 2.16 billion nm = 2160000000 nm
Shaquille O'Neal's height= 2160000000 nm
= 2.16 × 10^9 nm
Pretend these are coordinates that you can use to find the slope of the line.
(10, 40) and (15, 60). Fit these into the slope formula to find the slope of the line you are looking for:
and the slope is 4. Now use one of the points and the slope of 4 to solve for b, the y-intercept:
40 = 4(10) + b so b = 0. The equation of the line then is y = 4x + 0 or just
y = 4x
