X^2 + 14x + 45 = 0
(x + 5)(x + 9) = 0

x + 5 = 0
x = -5

x + 9 = 0 <=== here is the error...step 2
x = -9

Triangles TAM is congruent to triangle HAM using the ASA postulate. Which two sides are congruent?
zlopas [31]

Answer:

\overline{AM}\cong \overline{AM}


Step-by-step explanation:

Given that triangle TAM is congruent to the triangle HAM.

We know that corresponding sides of congruent triangles are equal so we can write:

TA = HA

AM = AM

TM = HM


comparing these with given choices we see that, (AM = AM) is the only matching answer.

Hence final answers is the first choice  \overline{AM}\cong \overline{AM}.

Hailey solved the problem 2.55 ÷ 1.5 and got the quotient 0.17. Her work is below. Is Hailey’s process Correct? Use mathematics
Evgesh-ka [11]

When Hailey solved the problem 2.55 ÷ 1.5 and got the quotient 0.17, the process isn't correct as she should put the 1 before the point.

<h3>What is a quotient?</h3>

A quotient is a quantity produced by the division of two numbers in arithmetic. The quotient is widely used in mathematics and is also known as the integer part of a division, a fraction, or a ratio.

The number that is being divided (in this case, 2.55) is called the dividend, and the number that it is being divided by (in this case, 1.5) is called the divisor. The result of the division is the quotient.

This will be:

= 2.55 / 1.5

= 1.7

She made a mistake by writing 0.17.
