Answer:
62 units
Step-by-step explanation:
The absolute value of a number A is the positive distance between 0 and the number A (you can think this distance as the distance measured with a ruler from 0 to the number). For example:
|-2|=2 , |25|=25, |-3|=3, |-25.3|=25.3
Note that the absolte value is always positive.
The distance between two numbers P,Q in the real line is the absolute value of the difference between the two points:
Hence, the distnce between P=-50 and Q=12 is equal to
The first 4 is forty, the second 4 is four. Both of them together are fortyfour (44)
Answer:
The expression is equivalent , but is not completely factored
Step-by-step explanation:
A student factors 3x² – 12 to the following. 3(x² – 4)
3x² – 12 is equivalent to 3(x² – 4), because 3 was factored out;
If we multiply by 3 by opening the brackets then we get the same expression 3x² – 12.
However; <em>3(x² – 4), could be factored further;</em>
<em>To get; 3(x + 2)(x - 2) ; since x² – 4 is a difference of two squares;</em>
<em>Therefore;</em>
<em>3x² – 12 = 3(x² – 4) = 3(x + 2)(x - 2)</em>
Answer:
Step-by-step explanation:
I think this is your full question:
<em>Ben sells handmade cards at a craft fair. He wants to earn more than $50 at the fair. He sells his cards for $2 and has already earned $36. How many cards does he need to sell to reach his goal? Explain why Ben would not meet his goal if he sold 7 cards. How could his goal be rephrased to include 7 cards?</em>
Because when Ben sells 7 cards, he will have $14 and with $36 he has already earn, he just has $50 in total, not more than that.
If he wants to earn more than $50, he needs to sell 8 cards at least.
