The answer is D. 3x^3+4x^2-11x+3
Answer:
The reciprocal is 25/12, therefore the number is 12/25, because 2 x 12 equals to 24, then plus 1, equals to 25, then it's 25/12. Not the best explanation but, better than no answer.
Step-by-step explanation:
7/15 in simplest form and 1 2/5 in mixed fraction, I'm not sure if this is right
Hey there :)
Let us change the sentence into mathematics:
Area of rectangle = 35 m²
Length of rectangle is 3 m more than twice the width = 3 + 3w
Width = w
We know the area formula of a rectangle
Area = length × width
Dimensions of the rectangle are:
35 = w ( 3 + 2w )
35 = 3w + 2w²
Take all values to one side and equate to 0
2w² + 3w - 35 = 0
Factor:
( 2w - 7 ) ( w + 5 ) = 0
w =
or w = - 5 ( Reject because lengths can never be negative )
Therefore the dimensions are:
Width = 3.5 mLength = 3 + 2 ( 3.5 ) = 10 m
Answer:
60
Step-by-step explanation:
To get to 300 from 15 you times 15 by 10 and then by 2, do the same for the number of students who like icecream
