The answer is no. because is you substitute the value 3 in for x into the equation and solve you get,
4(3)+3=18 which says 12+3=18 15=18 and that is an untrue statement.
Hope this helps explain the concept so you understand! Any questions feel free to ask! Please rate if I helped you! thank you so much!!
Answer:
The Answer is 3 - sqrt7
Step-by-step explanation:
2/3 + sqrt7 the starting equation
You multiply it by the conjugate which is 3 - sqrt7
= 2(3 - sqrt7) / (3 + sqrt7) (3 - sqrt7) the equation after you multiply by 3 - sqrt7
(3 + sqrt7) (3 - sqrt7) = 2
= 2(3 - sqrt7) / 2 the equation after you simplify (3 + sqrt7) (3 - sqrt7)
Divide out the 2's
= 3 - sqrt7/1 the equation after you divide out the 2's
= 3 - sqrt7 is THE ANSWER
Volume = Length x width x height
Volume = 5 1/2 x 3 x 3 = 49.5 cubic feet
The answer would be E because as you may know, 10 mm is equal to 1 cm. So, 230 mm³ is equal to 23 cm³.
