Step-by-step explanation:

sqrt(20)

sqrt(4*5)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(4) sqrt(5)

2 sqrt(5)

Answer:

We can factor down 20 with it's greatest prime GCF, which is 5. We get a 4. When we factor that down the same way, we get 2. If we repeat that process, we get 5, 2, and 2, which turns into 2√(5).

The midpoint of AB is M(-4,0). If the coordinates of A are (-6,4), what are the coordinates of B?

Answers

Answer:

B(-2,-4)

Step-by-step explanation:

Let coordinates of B be (x,y)

( ( - 6+ x)/(2) . (4 + y)/(2) ) = ( - 4.0) \n x = 2( - 4) + 6 \n x = - 2 \n \n y = 2(0) - 4 \n y = - 4

The steps below show the incomplete solution to find the value of y for the equation 4y − 2y − 4 = −1 + 13:Step 1: 4y − 2y − 4 = −1 + 13
Step 2: 4y − 2y − 4 = 12
Step 3: 2y − 4 = 12

Which of these is most likely the next step?

2y = 3
2y = 8
2y = 16
2y = 18

Answers

The next step would be:


2y - 16

Answer:

2y=16 Or the Third Option

Step-by-step explanation:

Trust me because i just got done doing my test and i got the question correctly.

Glenn has 450 stamps that are red blue green. 52% are red. He has 3/5 as many green as blue stamps. How many are blue and how many are green.

Answers

Since it is already stated that 52% of the 450 stamps are red (which is 234), the remaining 216 stamps are composed of blue and green stamps only. From there, we can write the equation:

216 = b + g
where:  b = blue stamps; g = green stamps

Applying the relation that the green stamps are 3/5 as much as the blue stamps, we can say that g = 3/5 b

Substituting the relation to the equation:
216 = b + 3/5 b
216 = 8/5 b

Dividing both sides by 8/5:
216/ (8/5) = 8/5 b / (8/5)
b = 135.

Going back to the equation and substituting the value of b:
216 = b + g
216 = 135 + g

Subtracting 135 from both sides to get g:
216 - 135 = 135 - 135 + g
g = 81

Therefore, there are 135 blue stamps and 81 green stamps.
