Answer:
126
Step-by-step explanation:
uhhhhh straight up guessed, but yeah heres the answer
6 - r = 2 (subtract 6 from both sides)
Your left with: -r = -4 (divide each side by -1)
Answer: r = 4
If you are solving for x then here’s how:
(3x2 + 4x - 12) = (x + 5)
Remove the x on the left by remove one x from both of the sides.
(3x2 + 3x - 12) = 5
Add 12 onto both sides
(3x2 + 3x) = 17
Multiply
(6 + 3x) = 17
Take away 6 from both sides
3x = 11
Divide by 3 on both sides
x = 3.666 recurring
I would simply consider saying that the answer is:
B. .533
because 8, 9-10th graders watched and 7 didn’t
Giving the answer to your homework is too easy, try splitting up the square into triangles. If you know angle A then split it in half (getting 20) and then calculate the missing value at corner C, multiply it by 2 and you get the value for the entire C. Now you know 3/4 angles.
