please help me with this math problem, the question is on the picture that i attached, ill mark brainliest if the answer is correct. NO links!

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

part a: 1.08

part b: 27.59

ιт ωιℓℓ gσ

5,-10,20,-40,30,-60

нσρє ι ¢συℓ∂ нєℓρ

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
