We can distribute
2(5)+2(-x)=10-2x
we get
8+10-2x=?
18-2x=?
whatever that ? is, we don't know
multiply both sides by -1
2x-18=-?
add 18 to both sides
2x=18-?
divide bth sides by 2
x=9-(?/2)
whatever the left side it, just divide it by 2 and subtract it from 9
Answer:
Step-by-step explanation:
the first choice has a negative 7 and the second choice has a negative 161 these are both negatives in different places which cause a different reaction
Answer:
15 m
Step-by-step explanation:
First split the shape into a square and a triangle, then find the area of the square by multipliyng the sides to get.
Next find the length of the traignel by subtracting 3 from 9 to get for then find the area of the triangle by multiplying 4 by 3 to get 12 then divide by 2 to get the area which is 6.
Finally add the 9 to the 6 to get 15
3 * 3 = 9
9 - 3 = 4
4 * 3 = 12/2 = 6
6+9=15
Answer:
16x^2 -48xy^3 +36y^6
Step-by-step explanation:
(4x-6y^(3))^(2)
FOIL
(4x-6y^3) (4x - 6y^3)
first: 4x*4x = 16x^2
outer : 4x (-6y^3) =-24xy^3
inner : 4x (-6y^3) =-24xy^3
last: -6y^3 * - 6y^3 = 36y^6
Add them together
16x^2 -24xy^3-24xy^3+36y^6
Combine like terms
16x^2 -48xy^3 +36y^6
