Answer:

Step-by-step explanation:
Answer:
BC=5
Step-by-step explanation:
BC^2= AB^2 + AC^2
x^2= 4^2 + 3^2
x^2= 16 +9
x^2= 25
x=

x= 5
As indicated on the number line 1/3 is the same as 2/6 so we get
Answer: 2/6 + 5/6 = 7/6
9cd to the power of 2 over 78124
3x² + xy2 – 3xy-y? >> 3x² - xy - y
line 1: = (3x² + xy2)+(-3xy – y?)
ANS 3x² - xy - y 《Correct》
line 2: = x(3x + y2) - y(3x – y2)
ANS 3x² - xy +2y²
line 3: = (x-y) (3x +y?)
ANS 3x² - 2xy - y²
If it incorrect, I'm sorry.
