Step-by-step explanation:
x = 7
3 + 4x = 5x - 4
3 + 4(7) = 5(7) - 4
3 + 28 = 35 - 4
31 = 31
Option C
Answer:
±2sqrt(10) = x
Step-by-step explanation:
40 - x^2 = 0
Add x^2 to each side
40 - x^2+x^2 = x^2
40 = x^2
Take the square root of each side
sqrt(40) = sqrt(x^2)
±sqrt(40) = x
±sqrt(4) sqrt(10) = x
±2sqrt(10) = x
Answer:
1. Right Triangle
2. Not Right Triangle
3. Not Right Triangle
Step-by-step explanation:
1. 28² + 45² = 2809 --> 53² = 2809
2. 6² + 6² = 72 --> 8² = 64
3. 4² + 10² = 116 --> 12² = 144
Sinx = 4/5, cosx = 3/5 and tanx = 4/3
