X=4 because you combine 2+4 and subtract -6 then divide
Answer: you can only add like terms, for example; 2x + 3x = 5x as they both have an x next to the numbers.
you cannot simplify 2 + 4x as they both don’t have an x next to them.
hence why, the answer to 2x^2 + 15x^2 would be 17x^2

Answer:
Option C is correct.
The test statistic for this question is -3.13
Step-by-step explanation:
To compute the z-test statistic, the formula is given as
z = (x - μ₀)/σₓ
x = p = sample proportion of the 500 college students sampled, that favor reducing the deficit using only spending cuts with no tax increase = (75/500) = 0.15
μ₀ = p₀ = the proportion to be compared against, that is, the proportion of Americans that favor reducing the U.S. budget deficit by using spending cuts only, with no tax increases = 20% = 0.20
σₓ = standard error of the sample proportion = √[p(1-p)/n]
p = 0.15
n = Sample size = 500
σₓ = √[0.15×0.85/500] = 0.01597
z = (0.15 - 0.20) ÷ 0.01597
z = -3.13
Hope this Helps!!!
-6+3=-3
-6-3=-9
so -3 and -9
