The length of each square on the grid represents 1 cm. The scale
1 answer:
Answer:
Step-by-step explanation:
Length of the rectangle given in the the figure attached = 2 cm
Width of the rectangle = 5 cm
Scale used, 24 in to 1 cm
Therefore, length of actual rectangle = 2×24 = 48 in
width of the actual rectangle = 5×24 = 120 in
Now we have to draw a drawing by using the scale,
16 inches to 1 cm
Or 1 inch = cm
Therefore, length of the rectangle drawing =
= 3 cm
Similarly, width of the rectangle drawing =
= 7.5 cm

Answer:
1) 5 2) 6 3) 1.25 or -1.75
Step-by-step explanation:
1. x^2 - 25 = 0
x^2 - 25 = 0
First, add 25 to both sides!
x^2 = 25
Now square root both sides.
x = 5
2. (x-2)^2 = 16
First, square root both sides.
(x-2) = 4
Add 2 on both sides.
(x) = 6
x = 6
3. Quadratic Formula = -b ± / 2a
Substitute in:
-6 ± / 2(2)
-6± / 4
Both forms:
-6 + / 4
5 / 4 = 1.25
Negative:
-6 - 1 / 4
-7 / 4 = -1.75
