the answer is A
Step-by-step explanation:
(9x2 + 10x +4) - (9x2 + 5x -1)
(22+10x) - (17+5x)
5x+5
The perimeter doesn't tell you the dimensions.
With a 40-ft perimeter, there an infinite number of possibilities
for the length and with. The only thing we know for sure is that
the sum of (length + width) is 20-ft.
The field could be . . .
1' by 40'
2' by 20'
3' by 13-1/3 '
4' by 10'
5' by 8'
6' by 6-2/3 '
Answer:
It means that the both sides of the expression in the given equation must be/are congruent.

Answer:
32
Step-by-step explanation:
4(5+3)=
20+12=
32
or
4(5+3)=
4(8)=
32
Answer:
a=15x; b=8x; c=13x
180°=a+b+c=15x+8x+13x=36x
=> x=180÷36=5
=> a=15×5=75°; b=8×5=40°; c=13×5=65°
