Donte used mental math to find the exact sum of 386 and 14. which strategy could donte have used? 1. 380 + 6 + 14 2. 380 + 14 + 14 3. 386 + 10 + 4 + 14 4. 386 + 14 + 80 + 6 plz me plz

answear:

a

step-by-step explanation: a

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
