B
rearrange into standard form : ax² + bx + c = 0 (a≠ 0)
2x² - 3x - 2 = 0
(x - 2)(2x + 1) = 0 ( equate each factor to zero and solve for x )
x - 2 = 0 ⇒ x = 2
2x + 1 = 0 ⇒ x = - 0.5
Answer:
x=1.833
Step-by-step explanation:
Let n represent the interger l, the three consective intergers are represented by
The second one represent
Simplify both sides
The intergers are 16,18,20
It would be the second graph
Basically, we are to find the area of the television screen. Because a TV is rectangular in form, the formula for the area is written below:
A = L×W
The given dimensions are 64 inches in length and 52 inches in width. But that includes the edges. To compute for the screen area only, we subtract 4 inches (2 inches on both sides) to each dimension.
A = (64 - 2)(52 - 2)
A = 3,100 square inches
