plz solve this fastly and I will mark u as brainliest.. plz solve this fast it's very urgent​

Answer 1

Answer:

1) a)3x+20+4x

   b)4x+58+3x

2)a)49y+5+3y

  b)-4y+5+90y

  c)95y+5-8y-20y

3)no

4)Circle             π × r2                    r = radius of the circle

  Triangle     ½ × b × h            b = base  h = height

  Square             Side*Side            Side = length of side

  Rectangle       l × w                    l = length    w = width

   Parallelogram    b × h            b=base    h=vertical height

  Trapezium       ½(a+b) × h    a and b are the length of parallel sides

                                                                                                     h = height

    Ellipse               πab                     a = ½ minor axis  b = ½ major axis

hey mate here is a tip

variable = the letters in a equation , who's quantity is unknown ex=x,y,z etc

constants = the numbers in a equation ex = 1,2,3,9,97, etc

now pls mark as brainliest
