I would say A because you would have to convert 3/2 to a mixed number which would be 1 1/2
Answer:
x = -4/3 x = 1/2
x=0 x = -3/4
Step-by-step explanation:
(3x+4) (2x-1)=0
Using the zero product property
3x+4 = 0 2x-1 =0
3x= -4 2x= 1
x = -4/3 x = 1/2
x (4x+3) =0
Using the zero product property
x = 0 4x+3 = 0
x=0 4x=-3
x=0 x = -3/4
wouldn't you divide the numbers???? Thats what I remember in 6th grade.....
Answer:
width = length = 3 inches
height = 7 inches
Step-by-step explanation:
If x is the width and length of the base, and y is the height, then:
y = x + 4
The volume of the box is:
63 = x²y
The surface area of the box is:
93 = x² + 4xy
Substitute the first equation into the third.
93 = x² + 4x (x + 4)
93 = x² + 4x² + 16x
0 = 5x² + 16x − 93
0 = (x − 3) (5x + 31)
x = 3
y = 7
Use the second equation to check your answer.
63 = (3)²(7)
63 = 63
