Hello!
Your questions are quite simple:
A.
Area for rectangle [formula]: A=wl
So your answer is 3×(2x+5)
Explanation:
Since you only have a minimum amount of a number and variable all you have to do is multiply them both in order to get the area, however here we are only asked for an expression so basically, we are leaving out the answer and writing down the multiplication.
B.
3×(2×2+5) = 27
Explanation:
I think the first explanation is very similar to this one, so I think you'll understand it.
Hope this helped!
Thus, the width of the poster is 8.185 inches and the length of the poster is 13.185 inches.

What is Area of rectangle?</h3>
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.
Area of poster = l X w
w · l = 72
x · x + 5 = 72
x . x = 72 - 5
x · x = 67
x² = 67
√x² = √67
Width x ≈ 8.185
so, by adding 5 inches, we get that
L = x + 5 = 8.185 + 5
length L = 13.185
Thus, the width of the poster is 8.185 inches and the length of the poster is 13.185 inches.

There are two unknowns in this problem. To start, let's assign variables to each of them. Let x be the age of Jacob and y be the age of Isaiah. Then, we formulate equations based on the relationships stated.
x = 7 + y --> eqn 1
x + y = 63 --> eqn 2
Substituting eqn 1 to eqn 2, then solve for x and y:
(7+y)+y = 63
7 + 2y = 63
2y = 63 - 7
2y = 56
y = 56/2
y = 28
x = 28 + 7 = 35
Therefore, Jacob is 35 years old, and Isaiah is 28 years old.
