Answer:
f = 3
Step-by-step explanation:
8 = 2f + 2
-2 -2
6 = 2f
/2 /2
3 = f
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
40 I'm not quite sure but I think that might be the ANWSER!
Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle is 180 degrees.
Use the exterior angles theorem to find y.
The exterior angle y is the sum of the two remote interior angles:
The sum of angles on a straight line is 180 degrees.
