Answer:
Length: 12 cm
Width: 8 cm
Height; 7 cm
Step-by-step explanation:
We are told that the areas of 2 of the faces are 84cm² and 56cm².
Now, the side faces are 4 in total with 2 each having same areas.
Thus, it means they would have the same height.
Let's find the highest common factor between 84cm² and 56cm².
The highest number that can be divide each equally is 7.
Thus;
12 × 7 = 84 cm²
8 × 7 = 56 cm²
This means, the bottom part will measure 12 cm by 8 cm.
Thus, the complete measurement is;
Length: 12 cm
Width: 8 cm
Height; 7 cm
Let's check if it will give us a Volume equal to that given.
Thus;
Volume = 12 × 8 × 7 = 672 cm²
This is same as that given and so our dimensions are correct.
For this case we have to:
x: It is the variable that represents the number of compact discs.
The cost function must be found considering that each disk costs $7.13. So:
Thus, to find the total cost of "x" compact discs (in $) we substitute the number of discs in the cost function.
Answer:
Answer:
The third option is the correct statement.
Step-by-step explanation:
Here, we have to select the statement from the four options that explain how we can use coordinate geometry to prove the opposite sides of a quadrilateral are congruent.
From my point of view, the third option is the correct statement.
It gives, first we have to calculate the length of each of the opposite sides using the distance formula and then they have to be equal to prove the opposite sides are equal. (Answer)
