The equation for surface area is 2(lw+lh+wh) or length times width plus length times height plus width times height times 2.

so in this problem legth=5 and width=4.5 so 5×4.5=22.5

length=5 height=3.5 so 5×3.5=17.5

width=4.5 height=3.5 so 4.5×3.5=15.75

add these together and you get 55.75.

now we multiply that by 2 so 55.75×2=111.5

so the surface area of the gift is (drumroll please) 111.5

<h3>Answer:  (x+1)(x+3)</h3>

===================================================

Explanation:

Let's assume it factors into (x+a)(x+b)

The goal is to find the two numbers a and b.

FOIL out (x+a)(x+b) to get x^2+(a+b)x+ab

Note how a+b is the middle term and ab is the last term.

In the original expression, 4 is the middle term and 3 is the last term.

So we need to find two numbers that

  • add to 4
  • multiply to 3

There are two ways to multiply to 3 and they are

  • 1 times 3 = 3
  • -1 times -3 = -3

But only the first way has the factors add to 4. So that means a = 1 and b = 3.

Therefore (x+a)(x+b) = (x+1)(x+3)

And x^2+4x+3 = (x+1)(x+3)
