Calculate the value of A in the triangle below

a = 3

Step-by-step explanation:

a² =5² - 4² = 25 - 16 = 9

a = 3

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

if x decreases by 4 then y increases by 10
