Answer:
20 ft
Step-by-step explanation:
If you count how many unit’s there is on the picture then multiply by 2, you get 20
Perimeter of a rectangle= 2(length)+2(width)
Data:
Perimeter=108 cm
length=18 cm
therefore:
108 cm=2(18 cm)+2(width)
108 cm=36 cm+2 (width)
2 width=108 cm -36 cm=
2 width=72 cm
width=72cm/2
width=36 cm
Answer: the width of the picture frame would be 36 cm.
Answer:
B
Step-by-step explanation:
Answer: 1 Real Root
Step by Step Explanation:
The discriminant uses the formula b^2-4ac. (^ means an exponent, b squared up above)
a=1, b =4, c=4 sub in those values into the formula.
(4)^2-4(1)(4) = 0
Since the answer is 0, the equation will have 1 real root.
