Answer:
<em>3.36in</em>
Step-by-step explanation:
The total surface area of the cardboard is expressed as;
TSA = 2(LW + LH + WH)
L is the length = 4in
W is the width
H is the height = 7in
TSA = 130in²
Substitute the given values into the formula and get the width W
TSA = 2(LW + LH + WH)
130 = 2(4W+4(7) + 7W)
130 = 2(11W+28)
130 = 22W+56
22W = 130 - 56
22S = 74
W = 74/22
<em>W = 3.36in</em>
<em>hence the width of the photo is 3.36in</em>

Step-by-step explanation:
x-3x can be simplied to -2x and 3-9 can be simplied to -6
-2x+4=-6
Substract 4 from both sides
-2x=-10
Divide both sides by -2
x=5
