The answer is <span>49x2 _ 84x + 36
</span>
(7x - 6)² is the square of the difference. The general formula would be:
(a - b)² = a² - 2ab + b²
In our expression (7x - 6)², a would be 7x and b would be 6:
(7x - 6)² = (7x)² - 2 · 7x · 6 + 6²
= 7² · x² - 84x + 36
= 49x² - 84x + 36
What is the probablity for the number of times Jada will pull a tile wit a star?
Answer: Number of tiles pulled out of the bag by Jada = 10, so she completed 10 trials.
The outcome of each trial was star, circle or a square.
Step-by-step explanation: We can find the experimental probability of pulling each shape from the bag based on the outcomes of Jada's experiment and number of trial.
- P(Star) = Number of stars/Number of trials= 5/10
- P(Circles)= Number of circles/Number of trials =3/10
- P(Square) = Number of Square/Number of trials = 2/10
Here, P refers to Probability of an outcome
If Jada repeats the experiment, She would likely again pull more stars than circles or square. She may get different number of stars,circles or squares but over a large number of trials, she would expect the ratio of the stars in the proportion. We can use this proportonal relationship to get the reasonable prediction about te number of times she pull different shape tiles.
<u>Number of outcomes(10 trials) </u> = <u>Number of outcomes(100 trials)</u>
Number of trials(10 trials) Number of trials (100 trials)
- Numbeof stars = 5/10 =s/100
5*10/ 10*10 =50/100 - Number of Circle = 3/10 = c/100
3*10/10*10 = 30/100 - Number of square = 2/10 = q/100
2*10/10*10 = 20/100
If she does the experiment 100 times then she should expect to pull out 50 stars tile, 30 circles and 20 Square.
Hence, Jada pulled out the 100 tiles from the bag.

Answer:
1) b would be easier because it’s 1/2bh and since the base of 10 is easily divisible by 2 you don’t have to deal with fractions.
D=sqrt (x2-x1)^2+(y2-y1)^2
D=10

Step-by-step explanation:
Keegan is correct.
Put a decimal point after the first digit which is 7. Count decimal places there are after the 7, this will be your power of 10. There are 18 decimal places after the 7. This means the answer would be 7 x 10^18.
