Answer:
Here is your answer
Step-by-step explanation:
3.(x+3)(x+5)
4.(x-8)(x+8)
5.(x+6)^2
X+y=11
x is longer than y
x>y
x is 4 less than 4 times y
x=-4+4y
sub back
x+y=11
-4+4y+y=11
-4+5y=11
add 4 to both sides
5y=15
divide both sides by 5
y=3
sub back
x=-4+4y
x=-4+4(3)
x=-4+12
x=8
the pieces are 8ft and 3ft
Both numbers have the variable x so you add 5 and 12 which gives you 17 and you need to write the variable. The answer is 17x
When you add integers, you keep the sign on the sum.
For example:
-9 + -9 = -18 (kept the sign)
9 + 9 = 18 (kept the "sign")
