Explain why each statement is true: 1.) 5 + 2 + 3 = 5 + (2 + 3)
2.) 9a = 11a - 2a
3.) 7a + 4 - 2a = 7a + -2a + 4
4.) 8a-(8a - 8) = 8

Cause it is!

Step-by-step explanation:

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

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
