Answer:
12
Step-by-step explanation:
if R = 9
9-8=1
9 + 3 = 12
12*1=12
Answer:
x<3 AND x>2
Step-by-step explanation:
First, 4x-4<8. Adding 4 to both sides, 4x<12, and dividing by 4, x<3.
Next, 9x+5>23. Subtracting 5 from both sides, 9x>18, and dividing by 9, x>2.
Therefore, x<3 AND x>2.
Answer:
It's the law of cosines
Step-by-step explanation:
law of cosines states that 
so we know that a = 7, b = 4, and alpha would be 135 degrees, so just plugging it in gets us 49+16-2*7*4*(-0.707) = 65 + 39.59 = 104.59
Answer:
1. DF (option 3)
2. segment addition postulate
3. segment congruence postulate
4. DF (option 5)
Answer:
p=2
Step-by-step explanation:
(3+6i) and (4+pi) is (7+8i)
3+4 = 7
6i+pi = 8i
Subtract 6i from each side
pi = 8i-6i
pi = 2i
That means p = 2
