Answer: 2 inch dimension will give smallest increase.
Step-by-step explanation:
Length = 3 in
width = 2 in
height = 6 in
Extra cardboard means to find surface area
on doubling the length
length = 6 In
width = 2 In
Height = 6In
Surface area for the above dimensions = 2 [ 6x2+2x6+6x6] = 120 sq in
On doubling the width
length = 3 in
width = 4 in
Height = 6 inch
Surface area for the above dimensions= 2 [ 3x4+4x6+6x3] = 2[54] = 108 sq inches
On doubling height
Length =3 in
width = 2 in
Height = 12 in
Surface area for above dimensions = 2 [ 3x2+2x12+12x3] = 2[6+24+36] = 132 sq inch
On doubling width surface area is minimum.
Answer:
No solutions
Step-by-step explanation:
If we try to solve this system for y at x = 1, we get an impossible situation:

Clearly, 1 ≠ -15, and we'll see that any value of x that we pick gives us two contradictory values for y, so this system has no solutions.
Answer:
B: 375 ft^2
Step-by-step explanation:
20 x 15 + 10 x 15/2 = 375
Answer:
(x-2 )= 18
(4xt1) = 81
i got it because x=20 mark branliest if you can thanks
Answer:
The correct option is 2. The given function is a polynomial of degree 4 with a leading coefficient of 36.
Step-by-step explanation:
A polynomial function is defined as

The given function is

Using perfect square trinomial property.
![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)
Using distributive property, we get



The given function is a polynomial of degree 4 with a leading coefficient of 36.
Therefore the correct option is 2.
