What is a 90° plus 180° plus 15°​

285°

Step-by-step explanation:

90 + 180 = 270

270 + 15 = 285

285°

Step-by-step explanation:

Lets solve your problem :)

90° + 180° = 270°

270° + 15° = 285°

Mark my answer brainliest to tell you the 4 algebra calulators :)

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
