Answer:
2a² + 2ab , 6x²y - 9xy²
Step-by-step explanation:
using the distributive property
a(b + c) = ab + ac
given
2a(a + b) ← multiply each term in the parenthesis by 2a
= 2a² + 2ab
given
3xy(2x - 3y) ← multiply each term in the parenthesis by 3xy
= 6x²y - 9xy²

Answer:
(21,5)
Step-by-step explanation:
To find the slope that passes through the points (7,5) and (21,15) , we use the formula
m = (y2-y1)/ (x2-x1)
= (15-5)/(21-7)
= 10/14
=5/7
We want a slope that is 1/3 this slope so we will multiply by 1/3
5/7 * 1/3= 5/21
We know the slope and one point (0,0) we can use the same formula to figure out x and y
m = (y2-y1)/ (x2-x1)
5/21 = (y2-0)/ (x2-0)
Let the tops be equal and the bottoms be equal
5 = y2-0
5 =y2
and the bottoms
21 = x2-0
21= x2
We have the point
(21,5)
