Answer:
what is the question your asking?
(X-5)(2x+3)=x(2x+3)-5(2x+3)
=x*2x+3*x-5*2x-5*3
= 2x^2+3x-10x-15
=2x^2-7x-15
Terms are: 2x^2. ; -7x. ; -15
1. 2 (x + 3) = x - 4
2x + 6 = x- 4
2x - x = -4 - 6
x = -4 + -6 = -10.
x = 10
2. 4 (5x - 2) = 2 (9x + 3)
20x - 8 = 18x + 3
20x - 18x = 3 + 8
2x = 11
x = 11/2 = 5.5
x = 11/2 or 5.5
These are the Answers.

Answer:
6(x +8)
Step-by-step explanation:
Factorising:
6x + 48
Take 6 as common, Therefore:
6(x +8)
Because:
6 * x = 6x
6 * 8 = 48
therefore:
6x + 48 = 6(x + 8)
Hope it helped!!!
Answer:
I believe its (- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
