Answer:
336
Step-by-step explanation:
area = 1/2 * (a + b) * h
P. o. symm is at (-3, -1) it is the center of the circle.
7a+21=56
Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35
Your new equation will be
7a=35
Finally, divide by 7 on both sides:
7/7=1 and 35/7=5
your answer will be
a=5
Answer
Example 1 Solve for x and check: x + 5 = 3
Solution
Using the same procedures learned in chapter 2, we subtract 5 from each side of the equation obtaining
Example 2 Solve for x and check: - 3x = 12
Solution
Dividing each side by -3, we obtain
Step-by-step explanation: here is your anserw the let me know if it right
Answer:
solve for x, 5(x + 2) - 13 = -2(x - 10) + 3x + 1
D) x = 6
