Answer:
There are many ways to show it like-
Step-by-step explanation:
2/5 as it’s already shown, or you can use 2 divide by 5, many people use 2[5] that’s the ways they showed my in my school idk if its different for you
Not evenly, no. If you divide 4460 by 3 or 9, the answer comes out as a decimal
Remark
Are you sure you don't mean that (x - 7) is squared? The way you have written it indicates that it is squared. I'll treat it that way and you can leave a not if I am wrong.
Solution
(x - 7)^2 - 25 = 0 Add 25 to both sides
(x - 7)^2 - 25 + 25 = 25 Combine the left
(x - 7)^2 = 25 Take the square root of both sides.
sqrt(x - 7)^2 = sqrt(25)
x - 7 = +/- 5 Add 7 to both sides
x = 7 +/- 5
=========
x1 = 7 + 5
x1 = 12
x2 = 7 - 5
x2 = 2
Smallest x = 2
Largest x = 12
Answer:
Between 25 and -18 is 0.
Between -18 and -12 (in the corner) is again, 0.
Between -12 and -18 (left side corner, bottom) is 5.
Between 0 and -12 (top left corner) is -18.
Between 0 and 5 (top of page) is 25
Between 5 and -12 (bottom right corner) is 0
Between -18 and 25 (middle) is 5
Between -18 and 0 (middle) is -12
Between -12 and 0 (middle-left) is 5
Between -12 and -18 (not corner, but above it) is 25.
Step-by-step explanation:
I don't really have a explanation, other than elimination.
In the case that you presented, the ratio is
50/100 = (x1)^2 / (x2)^2
1/2 = (x1)^2 / (x2)^2
x1 : x2 = 1 : √2
^2 means squared
