Answer: 832 cm².
Step-by-step explanation:
1. To calculate the lateral area of the prism by using the net you must:
- Calculate the perimeter of the base:
Where l is the lenght and w is the width:
Then:
- Now you must multiply the perimeter by the height. The height is 13 cm.
Then, the lateral surface area is:
Answer:
- 15 is added to a number ...
- The sum of 15 and a number ...
Step-by-step explanation:
Answer:
x = 2 and x = -2
Step-by-step explanation:
The quadratic formula of a quadratic of the form ax² + bx + c is:
x = or x =
Here, our equation is: 3x² - 18 = -6. Let's move all the terms to one side:
3x² - 12 = 0
a = 3 and c = -12. Notice that since there's no x term, b = 0.
Plug these into the quadratic formula:
x =
or
x =
So, x = 2 and x = -2.
Answer:
7.50h = 205
divide both sides of equation by 7.5
h = 27.33 hours
If you round that number it will take about 27 hours to make $205
Answer:
(- 3, - 4 )
Step-by-step explanation:
Under a reflection in the line y = - x
a point (x, y ) → (- y, - x ) , thus
(4, 3 ) → (- 3, - 4 )
