For what values of x and y are the triangles congruent?
KatRina [158]
For y
since both triangles are congruent,
6y-8=2y+8
4y=16
y=4
For x
5x-5y=2y+7
since y is 4, substitute y to 4
so,
5x-5(4)=2(4)+7
5x-20=15
5x=35
x=7

Find the least common denominator x^4/x^2+2x+1 and -8/x^2+5x+4
Harman [31]

Answer:

(x + 4)(x + 1)(x + 1)   or (x + 4)(x + 1)²

Step-by-step explanation:

Factor both denominators and see what you are missing between them

(x^4)/[(x + 1)(x + 1)           -8/[x + 4)(x + 1)]

So in order to get a common denominator, we need

(x + 4)(x + 1)(x + 1) as a denominator, or (x +4)(x + 1)²

To estimate the percentage of a state's voters who support the current
Lady bird [3.3K]

Using the Central Limit Theorem, the percentage that is expected to be the closest to the actual percentage is:

A. The Tribune, at 68%.

<h3>What does the Central Limit Theorem state?</h3>

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean \mu = p and standard error s = \sqrt{\frac{p(1 - p)}{n}}, as long as np \geq 10 and n(1 - p) \geq 10.

From this, a larger sample size leads to a smaller error estimate. Since the Tribune had the largest sample size, option A is correct.
