The first step to solve the equation is to add 3 to both sides.
Answer: Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
Answer:
13 meters
Step-by-step explanation:
Adjacent sides form half the perimeter, so the sum of the unknown side and the given side is 34/2 = 17 meters.
4 meters + width = 17 meters
width = 13 meters . . . . . subtract 4 meters
Its the reflections over the Y and X axis. Then count how diagonal the line is
Part A: -x+y=5
+x +x
y=x+5
4x+x+5=10
5x+5=10
-5 -5
5x=5
x=1
1(-x) +y=5
-1+y=5
+1 +1
y=6
The solution is (1,6)
Part B:
-x+y=5
-1+6=5
5=5
4x+y=10
4(1)+6=10
4+6=10
10=10
