Answer:
x = 8
Step-by-step explanation:
Δ RST is equiangular since all 3 sides are congruent, thus
Each angle in the triangle is 60° , then
7x + 4 = 60 ( subtract 4 from both sides )
7x = 56 ( divide both sides by 7 )
x = 8

Answer with explanation:</h2>
As per given , we have
p= 0.457
n= 1033
Margin of error for 99% confidence : E= 4%=0.04
Confidence interval : ![p\pm E](https://tex.z-dn.net/?f=p%5Cpm%20E)
i.e. ![0.457\pm 0.04](https://tex.z-dn.net/?f=%200.457%5Cpm%200.04)
![=( 0.457- 0.04,\ 0.457+0.04)=(0.417,\ 0.497)](https://tex.z-dn.net/?f=%3D%28%200.457-%200.04%2C%5C%200.457%2B0.04%29%3D%280.417%2C%5C%200.497%29%20)
99% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt. = (0.417, 0.497)
Interpretation : We are 99% sure that the true population proportion of registered voters who are in favor of raising income taxes to pay down the national debt lies in interval (0.417, 0.497).

Answer:
Changing g(x) to this form: a(x-h) + k, we have:
g(x) = 4 (x+3)^2 - 6
Comparing this to the original equation, f(x) = x^2, we have the following transformations:
The graph is widened.
The graph is shifted left 3 units.
