They are there unit distance away from each other
I am going to do the first 2 problems and show my work that way you know how to do it yourself.
So first of all, the foil method:
(a+b) (c+d) = ac+ad+bc+bd
1. (3xy-1) (4xy+2) = (3xy*4xy) + (3xy*2) + (-1*4xy) + (-1*2)
(3xy-1) (4xy+2) = (12x^2y^2) + (6xy) + (-4xy) + (-2)
(3xy-1) (4xy+2) = (12x^2y^2) + (6xy-4xy) - 2
(3xy-1) (4xy+2) = 12x^2y^2 + 2xy - 2
2. <span>(2x-3y) (4x-y) = (2x*4x) + (2x*-y) + (-3y*4x) + (-3y*-y)
(2x-3y) (4x-y) = (8x^2) + (-2xy) + (-12xy) + (3y^2)
</span> (2x-3y) (4x-y) = 8x^2 + (-2xy-12xy) + 3y^2
(2x-3y) (4x-y) = 8x^2 - 14xy + 3y^2
I hope this helps!
Answer:
<u>The answer is m = 5</u>
Step-by-step explanation:
Let's solve the proportional equation, this way:
3/m-2 = 7/m+2
3 * (m + 2) = 7 * (m - 2) [Lowest common denominator (m + 2) * (m - 2)]
3m + 6 = 7m - 14
-4m = -14 - 6 (Like terms)
-4m = -20
m = -20/-4
m = 5
<u>The answer is m = 5</u>
Answer:
x=7 y=4
Step-by-step explanation:
couldnt really see the question but i hope this helps
Factor the following:
35 u v - 5 u - 56 v + 8
Factor terms by grouping. 35 u v - 5 u - 56 v + 8 = (35 u v - 56 v) + (8 - 5 u) = 7 v (5 u - 8) - (5 u - 8):
7 v (5 u - 8) - (5 u - 8)
Factor 5 u - 8 from 7 v (5 u - 8) - (5 u - 8):
Answer: (5 u - 8) (7 v - 1)
