I think it’s 1 Bc x is not a number and I learned it’s 1
Answer:
235
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9*12.5=112.5
rec 2: (13.5-5.5)*(19.5-9-7)=28
rec 3:7*13.5=94.5
Then:
112.5+28+94.5=235
The equation (3xsquared+ 14x + 20 = 0) has no real roots, so there are no factors made of only real numbers.
The factors are [ -7 plus and minus ( i x square root of 11 ) ]
" i " is the square root of -1 .
