3 consecutive even integers : x, x + 2, x + 4
x + (x + 2) + (x + 4) = -84.....combine like terms
3x + 6 = - 84.......subtract 6 from each side
3x = -84 - 6
3x = - 90...divide both sides by 3
x = -90/3
x = -30
x + 2 = -30 + 2 = -28
x + 4 = -30 + 4 = -26
so ur 3 numbers are : -26, -28, -30
E would be your answer because the two negatives become a positive
Answer:
a) 4
b) 2
Step-by-step explanation:
a) multiply the coefficients and add the exponents
(4)(1) · = 4
b) divide the coefficients and subtract the exponents
(14 ÷ 7) · = 2
