Answer:
Step-by-step explanation:
Two similar triangles.
10/26 = y/13
y = 5
x² = 13² - y² = 144
x = 12
Answer:
Step-by-step explanation:
22/7x4^2=50.28
3x3=9
50.28-9=41.28
That would be (171 + x) / 2....what u do to find the average is add up all the numbers, then divide by how many numbers there are.
Replace x with 2 and solve each equation:
1/2(2) + 4 = 1 + 4 = 5
2+ 6 -1/2(2) -2 = 8-3 = 5
The answer is:
both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
