Answer:=6x2+5x + −4/15
Step-by-step explanation:Let's simplify step-by-step.
8x2−3x+13−(2x2−8x+3/5)
Distribute the Negative Sign:
=8x2−3x+13+−1(2x2−8x+3/5)
=8x2+−3x+13+−1(2x2)+−1(−8x)+−1(3/5)
=8x2+−3x+13+−2x2+8x+−3/5
Combine Like Terms:
=8x2+−3x+1/3+−2x2+8x+−3/5
=(8x2+−2x2)+(−3x+8x)+(1/3+−3/5)
=6x2+5x+−4/15
Answer:
Well I figure you would use a ratio. we are given one when comparing 240 lbs to 180 calories for each mile:
240lbs/180calories = 1 mile
we.are.given another when saying a person. burns 36 calories in 1 mile. we don't know weight so we will say x lbs:
x/36calories = 1 mile
since they both equal 1 mile we know they are equal:
240/180 = 1 = x /36
we can get rid of the 1 in between and say:
240/180 = x/36
let's reduce first fraction
8/6 = x/36
cross multiply:
8*36 = 6x
divide both sides by 6
8*6 = x
x = 48
Step-by-step explanation:
44 / 3 2/3 = 12
the missing length (x) = 12
To simplify, remove the parentheses and combine like terms:
( y + 22) + 3
Y + 22 + 3
Answer: Y + 25
B and D if you multiply 13 by z it would be 13z and you can add 5 and 8 because they have the same variable equaling 13z
