If you plot the points, you'll see that it's a square with side 4.
A = s^2
A = 4^2
A = 16 units squared
Answer: 32
Step-by-step explanation:
1.) Write the initial equation: 2(9+7)
2.) Add the values in the parentheses: 2(16)
3.) Multiply the value in the parentheses by 2: 2(16) = 32
12(2a-3)=-4a+5
Remember to follow PEMDAS. Note the equal sign, what you do to one side, you do to the other.
First, distribute 12 to all terms within the parenthesis
12(2a) = 24a
12(-3) = -36
24a - 36 = -4a + 5
Add 4a to both sides, and add 36 to both sides
24a (+4a) - 36 (+36) = -4a (+4a) + 5 (+36)
24a + 4a = 5 + 36
Simplify
28a = 41
Isolate the a. Divide 28 from both sides
28a/28 = 41/28
a = 41/28
Simplify a
a = 1.46 (simplified)
