Answer:
First, 32 rounded to the nearest ten is:
30
Step-by-step explanation:
When rounding to the nearest ten, like we did with 32 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
X2 - 6x + 5
= (x - 3)^2 - 9 + 5
= (x - 3)^2 - 4
vertex is a minimum at (3, -4)

Answer:
c. Change the length of side CB to 8 feet
Step-by-step explanation:
If the figures are similar, the ratios should be the same
Take the side of the larger triangle over the same side of the smaller
PR PQ RQ
----------- = --------------------= ----------------
AC AB CB
7.5 5 10
----------- = --------------------= ----------------
6 4 9
7.5 /6 = 1.25
5/4 = 1.25
10/9 =1.1111(repeating)
The bases are not in the right ratio. RQ over CB = 1.25. Since RQ = 10 and the ratio is 1.25, we can solve for CB
10/CB = 1.25
Multiply by CB on each side
10 = 1.25CB
Divide by 1.25 on each side
10/1.25 = CB
8 =CB
The intersection of
is 
Explanation:
The expression is 
To determine the intersection of these two inequalities, let us solve the two inequalities separately.
Consider 
Subtracting both sides by 1, we have,
Also, consider 
Adding both sides by 4, we have,

Using these two simplified inequalities in the expression, we have,

Writing this in the interval notation, we get,

Hence, the intersection of the two interval is

Thus, the intersection of
is
