Answer:
A. 27°
Step-by-step explanation:
triangle PST is congruent to triangle LKR
<S corresponds to <K.
m<S = m<K = 27°
Answer : C integer
When adding square root 25 and -9 which type of number is the sum
square root (25) is a perfect square number
-9 is an integer. Integer is a whole number that is positive or negative or 0. -9 is a negative number so it is an integer
the value of 
Now we find the sum of 5 and -9
5 - 9 = -4
-4 is an integer
So the sum is an integer
The answer to your problem would be 10.
if two figures are congruent, each side is congruent to the same side on the other figure.
AB=FG; CD=HI; EA=JF
since CD=HI, and CD=10, then HI would also equal 10
Well, the answer will depend on whether the order will count or not (based on Permutations and Combinations). <em>If the order counts</em>, then we would use the formula for Permutations, which is:

Where n is the number of items you have, and r is the number of times you choose from the items.

Which simplifies to

Which simplifies to 15*14*13 (because all the numbers 1-12 in the factorial canceled out), which gets us the answer
2730.
Now, if you wanted to find the number of ways to order the toys without replacement (<em>order doesn't count</em>), you would use the formula:

The variables are still the same, but you are now multiplying by r!.

Simplifies to

Which simplifies to (using the same cancellation method above)

Dividing 2730 by 3! will get us an answer of
455.
Really, it depends on whether they are ordered or not. In this case (since you didn't specify whether the order mattered), the answer would be
455 or
2730.

Answer: Negative</h3>
======================================================
Explanation:
3/7 = 0.42857 approximately
Pick a number between that value and 5, not including either endpoint. Let's say we pick x = 2
Plug x = 2 into the f(x) function
f(x) = (x - 5)(2x + 7)(7x-3)
f(2) = (2 - 5)(2*2 + 7)(7*2-3)
f(2) = (2 - 5)(4 + 7)(14-3)
f(2) = (-3)(11)(11)
f(2) = -363
The actual result doesn't matter. All we're after is whether the result is positive or negative. We see the result is negative. This means f(x) is negative when 3/7 < x < 5. The f(x) curve is below the x axis on this interval.
