.125 would be 8 as a whole number
S = 7x^2....divide both sides by 7
1/7s (same as s/7) = x^2...now take sqrt of both sides
(+ - ) sqrt 1/7s = x
Answer:
1 = 52
2 = 68
3 = 40
4 = 25
Step-by-step explanation:
1 = (4 + 3)^2 + (12 / 4)
7^2 + 3
49 + 3
= 52
2 = (12 x 9 - 7^2) + 9
(108 - 49) + 9
59 + 9
= 68
3 = (30 - 2) / 7 + 6^2
28 / 7 + 36
4 + 36
= 40
4 = (2 x 7 + 4^2) - 5
(14 + 16) - 5
30 - 5
= 25
Hope this helps!! Brainliest plz??
By the pythagorean theorem:
h^2=x^2+y^2, h is the diagonal, and x and y are the sides so...
d^2=s^2+(3s)^2
d^2=s^2+9s^2
d^2=10s^2
d=s√10 (since 10=2*5 neither of which is a square so √10 cannot be simplified any further)
The diagonal is s√10 units
