Answer:
$5202
Step-by-step explanation:
The total surface area of the cuboidal hall is:
2LB + 2BH + 2LH.
This will be: 2(40*3) + 2(3*15) + 2(40*15)
which will give : 1530m square.
The cost of 25msq of paint is 10
then the cost of 1530 will be 1530x10/25 = 612.
The cost of 1msq of tiles is 3
then the cost of 1530 will be 1530 x 3
= 4590.
Then the total cost will be =$5202
Answer:
the point where the graph crosses the y -axis
Step-by-step explanation:
Because a function must pass the vertical line test, a function can have at most one y -intercept.
This is a simultaneous equation. its saying there are two numbers (x and y) that satisfy both equations. Rearrange the 2nd equation to get x=30/y and substitute this into the first equation to get y=(30/y) +13. solve this for y and then you can solve for x.
Answer:
x = -3
x = 7
Step-by-step explanation:
If either term is zero the product is zero
(2x + 6)(x - 7) = 0
2x + 6 = 0
2x = -6
x = -3
x - 7 = 0
x = 7
