How is breaking apart the problem 16x34 like solving four simpler problems?

1 answer:

3 0

Since we know that 2*2*2*2=16 and 2*17=34, we can write it out as 2*2*2*2*2*17. Since 2*2=4, we can rewrite it as 4*4*2*17=16*2*17=32*17. To get this, we can separate 17 into (10+7) and using the distributive property we get 32(10+7)=32*10+32*7=320+224=544.

The four problems can be written as 16*2*17, then 32*17, then 32*(10+7), then 320+224

What are the solutions to x2+14x+40=0

torisob [31]

Answer:x

2−14x+40=0 Factor x2−14x+40 using the AC method.(x−10)(x−4)

0 If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.x−10=0x−4=0 Set the first factor equal to 0 and solve.x=10Set the next factor equal to 0and solve....x=4

The final solution is all the values that make (x−10)(x−4)=0 true x=10,4
