1
= -20
Step-by-step explanation:
Multiple: 2/
3
* (-6) = 2 · (-6)/
3 · 1
= -12/
3
= -4 · 3/
1 · 3
= -4
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-12, 3) = 3.
In words - two thirds multiplied by minus six = minus four.
Multiple: the result of step No. 1 * 5 = -4 * 5 = -20
follow me
(x+7)(x-4)
= x^2 + 7x - 4x - 28
= x^2 + 3x - 28
answer
g = 3
78 times 42=3,276
72 times 53=3,816
3276+3826=7102
