a solid is composed of squares and equilateral triangles. its net is shown below:

a triangular prism and its net are shown. the net is three squares with side length 4 units. attached above and below the middle square are equal sized triangles.

the area of each triangle is 7 square units. the surface area of the triangular prism is square units. (input whole number only.)

62

Step-by-step explanation:

The side length of each of the three squares is 4 units.  This means the area of each would be 4² = 16 sq. units.  For the three, this means the total area is 16(3) = 48 sq. units.

The area of each triangle is 7 sq. units; this means together the area of the two triangles is 2(7) = 14 sq. units.

Together this makes the surface area of the prism 14+48 = 62 sq. units.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
