Answer 1

which of the following expression is equal to -30?

d)(-6)×(+5)

Answer 2

Answer:

To find:

A right expression among the given option which is equal to -30

Solution:

The right answer is option d) (-6)×(+5)​.

Step-by-step explanation:

Hence the given integer is -30 and we have to find the right expression whose product equals -30.

a) -20(-5×2) = -20*(-10) = 200 , here the answer comes in positive as two times negative is positive.

b) (6×10)-(6×5)= 60 - 30= 30

c) (2×5)+(4×5) = 10+20 = 30

d) (-6)×(+5)​ = -30, here one is a negative integer and one positive so the answer integer will be negative.

So, option d is a correct answer as the integer has one negative and one positive, and the - and + answers are negative.
