A. 504 units(squared) B. 436,8 units(squared)

C. 218 units(squared)

D. 283,2 units(squared)

D. 283.2 units²

Step-by-step explanation:

Surface area of the triangular prism = 2×Base Area + Perimeter of triangular base×height of prism

Base Area = ½*bh

b = 6 km

h = 5.2 km

Base area = ½*6*5.2 = 15.6 km²

Perimeter of triangular base = 6+6+6 = 18 km

Height of prism = 14 km

Plug in the values into the equation

Surface area of triangular prism = 2×15.6 + 18×14

= 31.2 + 252

= 283.2 km²

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

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
