Answer:
3d figures - "a three-dimensional shape can be defined as a solid figure or an object or shape that has three dimensions – length, width and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth." -Google
Some Examples are...
- cones
-cylinders
-cubes
-sphere

You meant to say x^2 - 49 and the second binomial is x^2 - 16.
x^2 - 49 = (x - 7) (x + 7).
Set each factor to 0 and solve for x individually.
x - 7 = 0
x = 7
x + 7 = 0
x = -7
Do the same for x^2 - 16.
Here is the set up:
x^2 - 16 = (x - 4) (x + 4).
Take it from here.
Her estimate is not reasonable.
Since she estimated 69%, you could do either of these options. You could...
A. Divide 242 (or .5) to show how much half off would be, then compare her estimate with half of 242 (121). OR...
B. Simply divide 242 by 69% (.69) and compaor her estimate to the exact amount (166.98).
I hope this helps!
The formula for slope is: m = (y2 - y1) / (x2 - x1) ---> m = (b - b) / (-a - a) = 0/(-2a) = 0
First, find your total sales. You do this by adding all the sales together, 2030+1540+1800=5370. Now, for each person, divide their sales by total sales.Lola) 2030/5370=203/537≈0.378=37.8%Ahmed) 1540/5370=154/537≈0.287=28.7%Tommy) 1800/5370=180/537=60/179≈0.335=33.5%
