Answer:
The actual area of the page will be 120 square inches.
Step-by-step explanation:
Janice is creating a page of scrapbook having vertices (2,1), (7,1), (7,7), and (2,7).
If we plot the points on the coordinate plane then we will see that the page is of a rectangular shape with length (7 - 1) = 6 units which is parallel to the y-axis and width (7 - 2) = 5 units which is parallel to the x-axis.
So, the area of the page is (6 × 5) = 30 square units.
Now, given that 1 square unit is equivalent to 4 square inches.
Therefore, the actual area of the page will be (30 × 4) = 120 square inches. (Answer)
Step-by-step explanation:
Firstly, there's a typing error at (x=1)². I assume it is (x-1)². If my assumption is correct,then:
x²-2x+1-4x=x²-2x+1
x²-6x+1-x²+2x-1=0
-4x=0
x=0
So we know that the word 'product' means multiplication, and that means that h and 4 are being multiplied. Also, one-fifth of x is another way of saying that one-fifth is being multiplied with x. So then we can construct the equation:

And we can then simplify this by taking out the multiplication sign:

And so since we do not know what x or h is equal to, this is as far as we can go.
This question uses the concept of the division.
Vivi, the band drummer, burns 765 calories in 3 hours. And she burns these calories at the same rate. Which means she burns the same amount of calories per hour.
Thus, the set up equation for this question will be:
Energy burnt in 3 hours=756 calories
Therefore, Energy burnt in 1 hour =
Calories.
Thus, the required answer is that Vivi burns 252 Calories of energy per hour while drumming.
