The residuals are the numbers shown next to each black line. Just total them:
15 + 10 + 11-10 +9 +10 +3-17-12 = 19.
The answer is B. 19
Answer:
x =
or 
Step-by-step explanation:
First, combine like terms. Like terms are terms with the same amount of the same variable.
(2x + 3x) - 7 = 42
5x - 7 = 42
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions
~
First, add 7 to both sides of the equation:
5x - 7 (+ 7) = 42 (+ 7)
5x = 42 + 7
5x = 49
Next, divide 5 from both sides of the equation:
(5x)/5 = (49)/5
x = 49/5
x = 9.8
If the square is 15 units on each side, then its diagonal would be √(15²)+(15)²=√450=15√2 ☺☺☺☺
