What is the volume of the prism given below? 14
12
A. 280 units3
B. 480 units 3
C. 840 units 3
D. 420 units3

c

Step-by-step explanation:

first multiply 12×5 and you get 60 then multiple 14×60 and you'll get 840

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

the discriminant is 64 + 4*1*12 = 112

this is prime.
