Answer:
Step-by-step explanation:
A
B is the correct answer.
We are adding the border of x thickness to all 4 sides of the table. This makes the new width of the table 36+x+x = 36+2x and the new length of the table 72+x+x=72+2x. To find the area, we multiply the length and width:
(36+2x)(72+2x) = 3006
Multiplying the binomials, we get:
36*72 + 36*2x + 2x*72 + 2x*2x = 3006
2592 + 72x + 144x + 4x² = 3006
Combining like terms gets us
2592 + 216x + 4x² = 3006
Subtract 3006 from both sides:
2592 + 216x + 4x² - 3006 = 3006 - 3006
-414 + 216x + 4x² = 0
Writing in standard form we have
4x²+216x-414=0

Step-by-step explanation:
Answer:
The first one
Step-by-step explanation:
Because the lines will only meet on one specific point. The second image is parallel meaning there is no solution and the third image has both line overlaying on each other meaning they have multiple solutions. So because the first image shows that the line will end up meeting off the graph we can assume that it has one solution
Answer:
h(-2) = -1
Step-by-step explanation:
h(x)=-2x-5
Let x= -2
h(-2)=-2*-2-5
= 4 -5
h(-2) = -1
