We need to solve the equation: w² + 9 = 6w
⇒ w² - 6w + 9 = 0
⇒ w² - 3w - 3w + 9 = 0 (Breaking 6w such that their product is 9w²)
⇒ w × (w - 3) - 3 × (w - 3) = 0 (Extracting common factors)
⇒ (w - 3) × (w - 3) = 0
⇒ (w - 3)² = 0
⇒ w = 3
Hence, the correct answer is 3, which is the second option from the replacement set
Answer:
2933.46666667
Step-by-step explanation:
It let me answer now
Answer:
The answer is choice B: 22.52 units.
Step-by-step explanation:
We use the Pythagoras's theorem which says for a right triangle with sides and hypotenuse :
In our case
So we solve for
Which is choice B.
for the volume do the equation length×width×height. so 10×4×2.75
