Randall is making a tablecloth for his dining room table. The table is 6 feet long and 3.5 feet wide. He also wants the tablecloth to have two triangular sections that fall off the edge of the table. The triangles need to be 3.5 feet wide and 1 foot tall.

What is the area of the completed tablecloth in square feet?

PLEASE HELP, PLEASE :)

the answer would be 24.5 feet squared

Step-by-step explanation:

if you multiply 6 by 3.5 you get 21 and if you multiply 3.5 by one you get 3.5. you divide that by two to get 1.75. now you add the area of both triangles to get 3.5. add 3.5 and 21 to get 24.5. sorry if this was confusing

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
