(-2x3 + 5x2 – x + 2) + (x + 2)

8

Step-by-step explanation:

(-2x3 + 5x2 – x + 2) + (x + 2)

(-6+5x2-x+2)+(x+2)

(-6+10-x+2)+(x+2)

(6-x)+x+2

6-x+x+2

6+2

8

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

95.03 is the answer. hope this !
