Hello!
To find the value of x, we need to solve for the value of x.
5 + 4x = 32 + 2x (subtract 2x from both sides)
5 + 2x = 32 (subtract 5 from both sides)
27 = 2x (divide both sides by 2)
x = 27/2
Therefore, none of the given x-values make this equation true.
Answer:
104
Step-by-step explanation:
2x^2+8x−5=0
This is written in the form
ax^2 + bx+c
a =2 b = 8 c=-5
The discriminant is
b^2 -4ac
8^2 - 4(2)(-5)
64 + 40
104
The discriminant is 104
Answer:
Width = 7 units
Step-by-step explanation:
Width = x
Length = 3x + 1
2x + 2(3x+1) = 58
2x + 6x + 2 = 58
8x = 58-2
x = 56/8
x = 7
To get the price marked up you would multiply 27 by 0.75, which is 75% of the cost, and then add it to 27 which would give you the $27+75% markup.
