Please help me with this question:)
tester [92]

Answer:

Ada is correct.

Step-by-step explanation:

Problems with Naman:

Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Division

Addition

Subtraction

~

The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.

Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.

Juli2301 [7.4K]

Answer:

the number of kilometers hiked in all is \frac{29}{21}

Step-by-step explanation:

The computation of the number of kilometers hiked in all is shown below:

= Erwin + Jericho

= \frac{5}{7} + \frac{2}{3}\\\\= \frac{15 + 14}{21}   \\\\= \frac{29}{21}

B. if the two surge protectors are arranged in​ parallel, what is the probability that a voltage surge will not damage the​ tele
Free_Kalibri [48]
<span>Let's first set the two surge protectors as p and q. In order to solve this question we would also need another variable: the probability x of working correctly when a voltage surge occurs. So, the probability that the voltage surge will not damage the TV is: 1 - 0.06^2 divide by x^2.</span>
