A (-2. 7) -4. 9
B (-2.7+(-.4- 4.5)
Only these A and B are equal to the expression above.
Answer
8.5
Step-by-step explanation:
43 - 3d = d + 9
43 = d + 3d + 9
43 - 9 = 3d + d
34 = 4d
34/4 = 4d/4
8.5 = d
btw its a bit rude just to delete my answer you shouldve just asked for me to show an explanation
Answer:
x =15 + 30n
Step-by-step explanation:
8cos(12x)+4=-4
Subtract 4 from each side
8cos(12x)+4-4=-4-4
8cos(12x)=-8
Divide by 8
8/8cos(12x)=-8/8
cos(12x) = -1
Take the arccos on each side
arccos(cos(12x)) = arccos(-1)
12x = 180 degrees
But we can go around in a circle of 360 and get the same result
12 x = 180+360n where n is an integer
Divide each side by 12
x = 180/12 +360n/12
x =15 + 30n
4.4652 square feet. you just multiply the two
