Solve using suitable property [name the property]
1]428 x[-23]+[-428]x(-223)
2] 105 x(-37)
85600
It is simple.
The property used is Distributive property.
=428 x [[-23] + [-223]
=428 x [[-23] + 223]
=428 x 200
=85600
please give me a like if you feel this answer helpful.

To solve these expressions, we can use the commutative property of multiplication, which states that the order of multiplication does not affect the result. Additionally, we can also use the associative property of multiplication, which states that the grouping of numbers being multiplied does not affect the result.
Let's solve the expressions step by step:
1) 428 x (-23) + (-428) x (-223)
We can rearrange the expression by using the commutative property:
= (-23) x 428 + (-428) x (-223)
Now, we'll multiply:
= (-23) x 428 = -9904
= (-428) x (-223) = 95344
Finally, we add the results:
-9904 + 95344 = 85440
Therefore, the solution is 85440.
2) 105 x (-37)
We can simply multiply the two numbers:
= 105 x (-37) = -3885
Therefore, the solution is -3885.
Saw this same question the other day.
Is there a reason why you are using square brackets and round brackets?
Is it simply
(428)(-23)+(-428)(-223) ?
If so, I am sure you have a calculator.
remember for the order of operation, the multiplication has to be done before the addion.
