Answer:

-4, -4, 3, 8, 8

Step-by-step explanation:

-4(5+(-2))=-4(5)+-4(-2)

This is because of the distributive property. You have to distribute the 4 to the 5 and the -2.

-4(3)=-20+8

This is because since both the 5 and the -2 are being multiplied by -4, you can combine the 5 and the -2 to get 3 and then multiply that by -4.

This means (-4)(-2)=8

This is because (4)(2)=8 and two negatives make a positive.

An acute triangle has two sides measuring 8 cm and 10 cm . What is the best representation of the possible range of values for t
Mekhanik [1.2K]

Answer:

the right answer is 2 < s< 18

Step-by-step explanation:

The Third side of the triangle must be greater than the difference of the other two sides which is 10 -8= 2 and smaller than the sum of the other two sides of the triangle which is 10+8= 18.

so third side should be greater than 2 and less than 18.

So right answer is 2 < s< 18

= 58

Hope this helps :)
