Answer:
4x^5−15x^3−11x−1
Step-by-step explanation:
Simplify the expression. 4x^5−15x^3−11x−1
It can be both because there are diffrent sizes
Y=-5x+9
3x+2(-5x+9)=4
3x-10x+18=4
-7x=4-18
-7x=-14
x=2
5(2)+y=9
10+y=9
y=9-10
y=-1
The answer is (2,-1) :)
T= total length
T=1 2/5 meters + 4 1/5 meters
add the whole #s and the fractions
T= (1+4) + (2/5 + 1/5)
T= 5 3/5 meters total
Hope this helps! :)
