Answer:
Step-by-step explanation:
<u>Use the Pythagorean theorem:</u>
<u>Verify this for each line:</u>
1.
- 28² + 45² = 53²
- 2809 = 2809
- Yes
2.
- 33² + 56² = 64²
- 4225 ≠ 4096
- No
3.
- 36² + 77² = 85²
- 7225 = 7225
- Yes
Answer:
The answer is 13x-7
Step-by-step explanation:
f(x) is x-7, and g(x) is 4x3. 4x3 can also mean 12x , because 4x3 is 4*x*3. So, f(x) can be replaced with x-7, and g(x) can be replaced by 12x. (x-7)+(12x) is 13x-7.
So
(x-4)^2=(x-4)(x-4)=x^2-4x-4x+16=x^2-8x+16
Answer:
Step-by-step explanation:
<u>Alternate interior angles measure same as per their property:</u>
- m∠3 = m∠6
- 3x - 5 = 5x - 25
- 5x - 3x = 25 - 5
- 2x = 20
- x = 10
