Break the number within the radical symbol into 2 numbers: another number and a perfect square (when multiplied, they get the original number).
An example would be 48. The square root of 48 can be evaluated by breaking apart 48 into 16 (a perfect square) and 3 (another number). The square root of 16 is 4, so you take this number out of the radical symbol. Leave 3 within the symbol as it cannot be further reduced.
√48 = 4 √3.
Answer:
C and D
Step-by-step explanation:
Use Pythagorean theorem to test
a^2 + b^2 = c^2 ? a and b are the shorter two sides c = longest side
Doing this for each data set shows C and D ARE rt triangles
Answer:
It's equal to itself. Here are the two ways to do this problem. ↓
Answer: <em>x</em>∈(5,∞)
Step-by-step explanation:
x-7>-2=(x-7)+7>-2+7=<em>x</em>∈(5,∞)
To solve we need to group all the variables on one side, and all the constants on the other side.
Meg makes a dot plot for the data 9, 9, 4, 5, 5, 3,<br>
4,5, 3, 8, 8, 5. Where does a gap occur?
Papessa [141]
The gap consists of the values 6 and 7.
Check out the dot plot below to see what I mean. We have one cluster on the left from 3 to 5. Then another cluster on the right from 8 to 9.
