Answer:
Option B, y = 2 Superscript x + 2 Baseline + 3
- Brainliest if this was helpful :)
Answer:
let the unit digit be x
and the tens digit be y
so x+y = 9 ---> y = 9-x
the number is 10y+x
the number reversed is 10x + y
3(10y+x) = 8(10x + y)
30y + 3x = 80x + 8y
22y = 77x
2y = 7x
2(9-x) = 7x
18 - 2x = 7x
18=9x
x=2
y=7
the number is 72
check:
number is 72
reverse is 27
is 3(72) = 8(27)
91.773
is your answer by the way
Answer:
2×6729=13458
Step-by-step explanation:
This is a fairly easy question. Just use the Pythagorean Theorem:
Leg squared + Leg squared = Hypotenuse squared.
In symbols: L² + L² = H²
So if you want to find out if a triangle is a right triangle, just plug in the numbers:
12² + 35² = 37²?
144 + 1225 = 1369?
1369 = 1369, so yes, the lengths of 12 cm, 35 cm, and 37 cm could be the lengths of a right triangle.
Hope I answered your question!
