Considering the expression 4x + 12 = 64, it is found that:
A. The problem is that you purchased x fried pastry, costing $4, plus a chocolate and a soda, costing $12, and the total purchase cost was of $64.
B. The solution is x = 13.
C. The solution means that you purchased 13 fried pastry.
<h3>Expression</h3>
The expression is presented as follows:
4x + 12 = 64.
A possible context for this problem is:
- x fried pastry are purchased, each costing $4, hence 4x.
- A chocolate and a soda purchased, costing a total of 12, hence 4x + 12.
- The total cost of the purchase was of $64, hence 4x + 12 = 64.
The number of fried pastry purchased is the solution to the equation, calculated as follows:
4x + 12 = 64
4x = 52
x = 52/4
x = 13 -> 13 fried pastry were purchased.

Answer:
9 sq. units
Step-by-step explanation:
dimensions of rectangle are (7-3),(8-3)
or 4,5
area of rectangle=4×5=20
area of bottom Δ=1/2×4×2=4
area of top Δ=1/2×3×3=9/2
area of right triangle=1/2 ×5×1=5/2
area of Δ HIJ=20-(4+9/2+5/2)
=20-(4+14/2)
=20-(4+7)
=9 sq. units.
or area of triangle =1/2
| 3 5 |
| 7 3 |
|6 8 |
|3 5 |
=1/2[(9-35)+(56-18)+(30-24)]
=1/2[-26+38+6]
=1/2[-26+44]
=1/2(18)
=9 sq. units.
