it is 24 because you are adding 18 and 6 the equation is 18 - (-6)
Answer:
8.49 inches
Step-by-step explanation:
x^2 + 7^2 = 11^2
x^2 + 49 = 121
X^2 = 121 - 49
x^2 = 72 (then take square root on both sides)
x = 8.49 inches
So if a increases, the x decreases.
Three consecutive even integers whose sum is -48
