Consider the equation |1/4+12|=x/2.Without calculating, how do you know x=-16 is an extraneous solution?

1 answer:

5 0

Without calculating, you can immediately see the absolute value sign, which implies that the final result (x) should be positive, not negative.

A rectangle sandbox has a width of 5 feet. Tbe sandbox is 5 times as long as it is wide. What is the perimeter of the sandbox?

NikAS [45]

The perimeter of the sandbox is 60 ft.
5x5=25
Two sides = 25, so 25+25 = 50.
Two other sides = 5, so 5+5=10
50+10 = 60, and that is the correct answer.

Since it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem. For the same reason, if m∠B < m∠C, then AC < AB. This is a contradiction to what is given. Therefore, it can be concluded that

Answer: Angle (B) is Congruent to Angle (C)
