Answer:
3√5
Step-by-step explanation:
The largest perfect square of the factors of 45 is 9. We can therefore convert √45 like this:
√9 × 5
Next, we separate the numbers inside the √ as such:
√9 × √5
√9 is a perfect square that equals 3. We can therefore put 3 outside the radical and get the final answer to square root of 45 in simplest radical form as follows:
3√5

Answer:
a.) Vertical Angles
b.) Given (Parallel)
c.) Substitution
Step-by-step explanation:
Answer:
1. Equivalent
2. Not equivalent
Step-by-step explanation:
1. Equivalent because there's 4 x's that you add all together and that makes 4x
2. Not equivalent because 5x means there's 5 x's or x + x + x + x + x not only 1 x plus a number 5
3x + 2y = 39
5x - y = 13
Multiplying the last by two:
10x - 2y = 26
Adding to the first
13x = 65
x = 5
y = 5x-13 =25-13=12
Check:
3(5)+2(12)=39 good
5(5)-12=13 good
Answer: x=5, y=12
