The answer is C, AB and BC are both radii of Circle B. You can tell by the way both lines come from the center of Circle B to the edge. AC is not a radii of Circle B, and AC is also not in the question.
Combine like terms with common variable to simplify an expression.
1) (0b +10) + 5(b + 2) = 10 + 5b + 10 = 5b + 20
2) -7(n + 3) - 8(1 + 8n) = -7n -21 - 8 - 64n = -71n - 29
Use the distributive property to expand the expression.
1) -6(3x - 8) = -18x + 48
2) (-m + 9)(-3) = 3m - 27
3) 3(-6 - x) = -18 - 3x
4) 2(x - y + 1) = 2x - 2y + 2
5) 4(6p + 2q - 2p) = 24p + 8q - 8p = 16p + 8q
6) p(m + 2) = pm + 2p
Answer:
<em>r = 6 </em>
Step-by-step explanation:
4r + 6r - 13 = 7r + 5
10r - 13 = 7r + 5
10r - 7r = 13 + 5
3r = 18
<em>r = 6</em>
