The area (in square centimeters) of a square coaster can be represented by d^2+8d+16 .
Katarina [22]

ANSWER

a. d+4

b. 4d+16

EXPLANATION

The area of the square coaster is represented by:

{d}^{2}  + 8d + 16

We split the middle term to obtain,

{d}^{2}  + 4d + 4d + 16

We factor by grouping to get,

d(d + 4) + 4(d + 4)

(d + 4)(d + 4) =  {(d + 4)}^{2}

Since area of a square is l² , it means the side length of the square is

l = d + 4

b) The perimeter of a square is given by

P=4l

We substitute the length in terms of d, to obtain;

P=4(d + 4)

Or

P=4d + 16

Solve the system of equations by graphing.
valentinak56 [21]
The answer is A.

The way you know this is by graphing the first function.

The second function is in a different format, so you just have to isolate Y. 

-1/3x + y = -1
y= 1/3x -1  OR y= -1 + 1/3x

both of the functions have the same slope, but different y-intercepts. therefore, they'll never touch. making them infinite solutions.

it's also A because both of the slopes are positive, the slopes in graph D are negative.

So, the answer is A.

Hope this helps! xx

Evaluate the function for x=4 <br> F(x)= x^3+2x^2+1
alukav5142 [94]

Answer:

F(4) = 97

Step-by-step explanation:

F(x)= x³+2x²+1

when x = 4

F(4)= 4³+2(4²)+1

= 4³+2(4²)+1

= 64 + 2(16) + 1

= 64 + 32 + 1

= 97
