What is the area of the rectangle if the side lengths are 3xy and 4x^2y^3

1 answer:

4 0

4x - 1 = side of square 2x + 1 = length of rectanglex + 2 = width of rectangleSince their perimeters are equal, 4(4x - 1) = 2(2x + 1) + 2(x + 2) 16x - 4 = 4x + 2 + 2x + 410x = 10x = 1If we plug 1 in for x,Each side of the square is 4(1) - 1 = 3The perimeter is thus 12 The length of the rectangle = 2(1) + 1 = 3The width of the rectangle is 1 + 2 = 3The perimeter is this 2(3) + 2(3) = 12 So x = 1 is the verified.

hope this helps! (:

I'm not sure about the 2nd question so you can use it if you want or just wait if someone else gives a different answer

25 × 0.52 = 13 pets that don't have a home

25 - 13 = 12 pets that have a home

Pets that don't have a home is more than the pets that have a home

The statement is not misleading

The values are 155 degrees, 5y degrees, and 13x degrees. find the values of x and y

katen-ka-za [31]

Answer:

y = 5

x = 5

Step-by-step explanation:

find the complete question in the attached image

the angle opposite 5y is also 5y. this is because alternate angles are equal

180 = 155 + 5y

5y = 180 - 155

5y = 25

y = 5

the sum of 5y and 13x is equal to 90

this is because the sum of angle on a straight line is equal to 180 and one of the angle on the straight line is already equal to 90 . so, 90 (180 - 90)

5y + 13x = 90

25 + 13x = 90

13x = 90 - 25

13x = 65

x = 5
