Answer:
x^2 + 4y^2 + 6x + 4
Step-by-step explanation:
Arranging the terms;
x ^ 2 + y^2 + 3y^2 + 4x + 2x + 2 + 2
x^2 + 4y^2 + 4x + 2x + 2 + 2
x^2 + 4y^2 + 6x + 2 + 2
x^2 + 4y^2 + 6x + 4
Answer: The number 5 in 56 is in the tenths place.
Answer:
E. When the sample size increases, because the standard deviation of the distribution of sample means better estimates the population standard deviation for larger sample sizes.
Step-by-step explanation:
- T distribution is similar to the normal distribution and is seen when the estimates of the variance are based on the degree of freedom and has a relatively more score in its tail and has a greater change of extreme values.
Answer:
First, we determine how many inches in the board. (5 x 12) + 3. This gives you 63 total inches. You want three equal pieces so you divide 63 by 3 and the answer is 21 inches for each individual piece.

To find equivalent equations, you simply have to simplify both of these :)
a) 5/6(x - 6) + 1/6(3 - x)
Simplify.
5/6x - 5 + 1/2 - 1/6x
Add like terms.
(5/6x - 1/6x) + (-5 + 1/2)
Simplify.
4/6x +(-4.5)
Simplify.
2/3x - 4.5
b) (y + 7)4 + 8 - 5y
Simplify.
4y + 28 + 8 - 5y
Add like terms.
(4y - 5y) + (28 + 8)
Simplify.
-y + 36
