Not really sure how to find xy :(

Answers

Answer 1

Answer: that's an equilateral triangle which means that all sides and angles are equal to each other. So now if you set everything equal to each other you get 2(2x+1)=6x+7y. Now it's just algebra after that, you have to distribute then left side then isolate the variable y and you get a y value. next step is pretty simple just substitute the answer that you got for y into the original equation that included y so you can get an x value. if everything is right it should tell you that the final answer is 14.

Find each percent increase or decrease to the nearest percent.1. from 14 books to 40 books
2. from 72 points to 50 points

Answers

Answer:

1. 185.71% 2. 30.56%

Step-by-step explanation:

(1) Initial no of books = 14

Final no of books = 40

Increase in books = 40-14 = 26

$\%\ \text{increase in books}=\frac{\text{increase in books}}{\text{initial no of books}}* 100\n\n=(26)/(14)* 100\n\n=185.71\%$

(2) Initial points = 72

Final points = 50

Decrease in points = 72-50= 22

$\%\ \text{decrease in points}=\frac{\text{decrease in points}}{\text{initial points}}* 100\n\n=(22)/(72)* 100\n\n=30.56\%$

Hence, this is the required solution.

To convert from square miles to square feet,what operation will you use

Answers

The correct one is multiplication.

-- Take the number of square miles.

-- Multiply it by the fraction (5,280 feet / 1 mile)² .

-- After canceling things where possible, simplifying, and
cleaning up the product, what you have is the same area
expressed in square feet.

Multiplication because to convert from a larger unit, miles, to a smaller unit, feet, you multiply the number of miles by the number of feet in a mile to get the total number of feet.

Please help quick

Answers

Answer:

Step-by-step explanation:

A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides. So a parallelogram is also a trapezoid. A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required. In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram). The diagonals are also of equal length.

A parallelogram has adjacent sides with the lengths of and . Find a pair of possible adjacent side lengths for a similar parallelogram. Explanation: Since the two parallelogram are similar, each of the corresponding sides must have the same ratio.

Not only are the corresponding angles the same size in similar polygons, but also the sides are proportional.
