The answer would be x=245 cm
Answer:
I believe the answer is c
Step-by-step explanation:
What i got tho was... 3x-5y=-20
In 8, 9, 10, all the triangles are similar, meaning corresponding sides have the same ratio.
8. hypotenuse / (short side) = 25/x = x/9
x² = 25*9 = 5²×3²
x = √(5²×3²) = 5*3 = 15
9. (long side) / (short side) = x/7 = 9/x
x² = 7*9
x = √(9*7) = 3√7
10. (short side) / (long side) = x/48 = 48/64
x = 48²/64 = 36
40,44,48,52,56,60 and so on. Just basically count by 4. Answer:
Step-by-step explanation:
7 - 2(x - 4)...when x = 5
7 - 2(5 - 4) =
7 - 2(1) =
7 - 2 =
5 <==
