Answer:
6X^2 -X -12
Step-by-step explanation:
(2X-3)(3X+4)
FOIL
first 2X*3X = 6X^2
outer 2X *4 = 8X
inner -3 *3X = -9x
last = -3 *4 =-12
Add them together = 6X^2 +8X -9X -12
= 6X^2 -X -12
Answer:
numbers are 24 and 210
Step-by-step explanation:
the number are : 24(2x2x2x3) and 210 (3x2x5x7)

Answer:
6x +10
Step-by-step explanation:
Perimeter = 2*(length + width)
= 2* (x+6 + 2x-1)
=2*(3x +5)
=2*3x + 2*5
