Answer:
3,4,5,6 and 7
Step-by-step explanation:
Given
Required
State the values of x within 2 and 8
Collect Like Terms
Divide both sides by 5
(2,8) is an open interval which means that 2 and 8 are not inclusive of the values of x.
So:
The values of are: 3,4,5,6 and 7
Answer:
Length = 16 inches and width = 12inches
Step-by-step explanation:
A = 192 in² . The width is 4 + 1/2x. therefore let x = length
Area = LW
192 = x(4 + 1/2 x)
192 = 4x + 1/2x²
384 = 8x + x² Multiply each term by 2 to make a
384 + 16 = x² + 8x + 16 Complete the square
400 = (x + 4)²
± 20 = x + 4
20 = x + 4 or -20 = x + 4
20 - 4 = x or -20 - 4 = x
16 = x or -24 = x reject the negative amount
Length = 16
width = 4 + 1/2(16); 4 + 8 = 12
