Step-by-step explanation:
DEFG ~ D'E'F'G'
= 
Answer:
x=−2 or x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x2−2x−3=5
Step 2: Subtract 5 from both sides.
x2−2x−3−5=5−5
x2−2x−8=0
Step 3: Factor left side of equation.
(x+2)(x−4)=0
Step 4: Set factors equal to 0.
x+2=0 or x−4=0
x=−2 or x=4
Step-by-step explanation:
due to the rules of crossing lines and their angles, the 2 angles opposite of each other must be equal.
so,
7x + 7 = 112
7x = 105
x = 15
