The answer for this would be A. the radius
19 x 4 is the equation and the answers is 76
Answer:
x = 12
Step-by-step explanation:
Step 1: Define
f(x) = 4x + 6
f(x) = 54
Step 2: Substitute variables
54 = 4x + 6
Step 3: Solve for <em>x</em>
<u>Subtract 6 on both sides:</u> 48 = 4x
<u>Divide both sides by 4:</u> 12 = x
Step 4: Check
<em>Plug in x to verify it is a solution.</em>
f(12) = 4(12) + 6
f(12) = 48 + 6
f(12) = 54
∠1 = ∠2
2x +10 = 3x -6
16 = x . . . . . . . . . . . add 6-2x
Selection B is appropriate.

Answer:
A- Cai are used an invalid reason to justify the congruence of a pair of sides or angles.
Step-by-step explanation:
In step 4, Cai referred to the angles as "alternate interior." In fact, they are "corresponding." The reason used to justify congruence of the angles was invalid.
