Answer:
The area of the square is 2.25cm
Step-by-step explanation:
Here's what we know:
-Each letter represent a side
-A square is made up of 4 congruent sides
-To find the area of a square you need 2 sides
-We have 2 sides (A and B)
Now we can solve:
If 3cm is the length of A and B together, then we can determine that separately The sides are 1.5cm. We can then multiply 1.5 by itself to get 2.25cm.
Hope this helps :)

How can you use x- and y- intercepts to graph an equation
Answer:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.

Evaluate 1 5y+ 1 10 when y= 1 2.
Answer:
290
Step-by-step explanation:
15(12)+110
290
Answer:
170
Step-by-step explanation:
1. y=12 is given so we should put this value in the equation 5y+110
2. then the equation will be 5x12+110
3. 5x12=60
4. 60+110= 170

A nationwide poll asked a random sample of US adults the question, “Are you in favor of making Election Day a federal holiday?” Based on the results of this poll, the 95% confidence interval for the population proportion who favor making Election Day a federal holiday is (0.64, 0.70).
Calculate the point estimate and margin of error for the given confidence interval.
Enter both values to 2 decimal places.
The point estimate =
The margin of error =
Answer: point estimate = 0.67 and Margin of error = 0.03 .
Step-by-step explanation:
For confidence interval,
Lower limit = point estimate - margin of error
Upper limit = point estimate + margin of error
Given confidence interval: (0.64, 0.70)
i.e. Lower limit = 0.64
Upper limit = 0.70
i.e. point estimate - margin of error= 0.64 (i)
point estimate + margin of error= 0.70 (ii)
Adding (i) and (ii) , we get
2( point estimate) = 1.34
⇒ point estimate = 0.67
Eliminate (i) from (ii) , we get
2( Margin of error ) = 0.06
⇒ Margin of error = 0.03
Hence, point estimate = 0.67 and Margin of error = 0.03 .
Answer:
Step-by-step explanation:
Question: A nationwide poll asked a random sample of US adults the question, "Are you in favor of making Election Day a federal holiday?” Based on the results of this poll, the 95% confidence interval for the population proportion who favor making Election Day a federal holiday is (0.64, 0.70).
Based on this poll, a reporter claims that more than three-fourths of U.S. adults favor making Election Day a federal holiday.

The figure shows three quadrilaterals on a coordinate grid: A coordinate grid is shown from positive 8 to negative 8 on the x axis and from positive 8 to negative 8 on the y axis. An image of a rectangle labeled E is shown on ordered pair negative 1, negative 1 and negative 3, negative 1 and negative 3, negative 2 and negative 1, negative 2. Another image of a rectangle labeled G is shown on ordered pair negative 2, negative 2 and negative 6, negative 2 and negative 6, negative 4 and negative 2, negative 4. Another image of a rectangle labeled F is shown on ordered pair negative 1, 1 and negative 1, 2, and negative 3, 2 and negative 3, 1. Which of the following statements is true about the three quadrilaterals? E and F are similar but not congruent. E and G are similar but not congruent. G and F are similar and also congruent. E and G are similar and also congruent.
Answer: E and G are similar and also congruent.

PLEASE HELP ME!!!!!
This is due tomorrow and I am struggling. I don’t understand anything my math teacher teaches. I’m online cause I don’t like going to school and Im trying to make the best of it. I never thought this year I would have a math teacher like this. Last year my math teacher was such a good teacher. I passed every test in her class it was a piece of cake. But this year I’m not so lucky. So I’m asking if anyone can HELP ME PLEASE!!!! Oh and as a reminder there’s two math problems. U going to have to click it cause it’s an photo.
Step-by-step explanation:
2.
(2 + √3)(2 - √3)
x² - y² = (x + y)(x - y)x = 2, y= √3x² = 2² = 4y² = √3² = 3(2 + √3)(2 - √3) = 4 - 3 = 13.
(6 + √5)/(6 - √5)
Multiply both numerator and denominator by (6 + √5) to simplify(6 - √5) ((6 + √5) = 6² - √5² = 36 - 5 = 31(6 + √5)/(6 +√5) = 6² + 2*6*√5 + √5² = 36 + 12√5 + 5 = 41 + 12√5(6 + √5)/(6 - √5) = (41 + 12√5)/31- 7x - 50 - 2. This is my question.

Find the value of y
Answer:
69 degrees
Step-by-step explanation:
The triangles are congruent because one of the angles is congruent to the other and the angle at the top is the same. The total number of degrees in a triange is 180. 180-(66+45 (the angle lenghts of the other 2 angles)) is equal to 180-111=69 degrees.
