Answer:
Option B and D
Step-by-step explanation:
Subtract 9 from both sides :
4x² + 4x - 8 = 0
Divide both sides by 4 :
x² + x - 2 = 0
Factorise using factorisation method :
x² - x + 2x -2 = 0
x(x - 1) +2(x-1) = 0
(x+2)(x-1) = 0
Solve for x
x +2 = 0 OR x - 1 = 0
x = -2 OR x = 1
Answer will be Option B and D
Hope this helped and have a good day
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

Answer:
what is the equation that u actually looking for?
Step-by-step explanation:
Answer: length = 4.5 m, width = 3 m
Step-by-step explanation:
When a shape is enlarged using a scale factor, you simply multiply each of the sides by the scale factor.
length = 3 * 1.5 = 4.5 m
width = 2 * 1.5 = 3 m
