A square photograph is printed on a larger rectangular sheet of paper leaving a border around the photograph of 3 centimeters on the top and 4 centimeters on each of the remaining sides. The sheet of paper has an area of 110 square centimeters. If x is the length of a side of the photograph measured in centimeters, which of the following equations could be used to find x? A. x^2 + 11x - 42 = 0
B. x^2 - 42 = 0
C. x^2 + 9x - 52 = 0
D. 11x - 42 = 0
E. x^2 - 11x - 42 = 0

The right equation will be "".

Step-by-step explanation:

According to the question,

Border around the photograph on the top is:

= 3 cm

The remaining sides,

= 4 cm

Area,

= 10 square cm

Let the length of sides be "x".

Since,

The paper's dimensions will be:

⇒

and

⇒

now,

⇒

⇒

⇒        

On subtracting "56" from both sides, we get

⇒        

⇒              

Or,

⇒      

36

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
