1/9, sorry if it’s wrong!! Hopefully it helps you!
STEP 1
Equation at the end of step
((14 • (x2)) - 7xy) - (3•72y2)
Equation at the end of step 2
((2•7x2) - 7xy) - (3•72y2)
STEP 3
STEP 4
Pulling out like terms
4.1 Pull out like factors :
14x2 - 7xy - 147y2 = 7 • (2x2 - xy - 21y2)
Trying to factor a multi variable polynomial :
4.2 Factoring 2x2 - xy - 21y2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (2x - 7y)•(x + 3y)
No. notice you have (3,-8) and (3,2). a function cannot have the same number on the left of the come (the x value) with different values on the right (h the y values)
Answer:
114 feet
Step-by-step explanation:
the black and white will both have the same area. and given that each path is 1 ft wide and initially 12 ft long we can slowly determine the area.
x times 1 will still equal x
12(1) still equals 12 so we can just write it as 12.
12+12+11+11+10+10+9+9+8+8+7+7= 114
where I came up with this? there are a total of 12 sides if you follow the black path. and by every 2 sides the path gets shorter by 1 foot.
the white side also has 12 sides if you look. therefore both the black and the white part of the shape will have an area of 114.
