Step-by-step explanation:
you are given both 10b + 19 and b = -2
lets plug in the value of b
10b(-2) + 19
multiply the 10b and the -2
-20b + 19
-20 + 19 = -1
-1
Let us determine the product of 438 and 17 by partial products.
Consider ![438 = 400+30+8](https://tex.z-dn.net/?f=438%20%3D%20400%2B30%2B8)
and ![17 = 10+7](https://tex.z-dn.net/?f=17%20%3D%2010%2B7)
So, ![438 \times 17 = (400+30+8) \times (10+7)](https://tex.z-dn.net/?f=438%20%5Ctimes%2017%20%3D%20%28400%2B30%2B8%29%20%5Ctimes%20%2810%2B7%29)
![438 \times 17 = (400\times 10)+(30 \times 10)+(8 \times 10) +(400 \times 7)+(30 \times 7)+(8 \times 7)](https://tex.z-dn.net/?f=438%20%5Ctimes%2017%20%3D%20%28400%5Ctimes%2010%29%2B%2830%20%5Ctimes%2010%29%2B%288%20%5Ctimes%2010%29%20%2B%28400%20%5Ctimes%207%29%2B%2830%20%5Ctimes%207%29%2B%288%20%5Ctimes%207%29)
= ![438 \times 17 = (4000+300+80+2800+210+56)](https://tex.z-dn.net/?f=438%20%5Ctimes%2017%20%3D%20%284000%2B300%2B80%2B2800%2B210%2B56%29)
= 7446
Therefore, the product of 438 and 17 is 7446.
No, Sandra's answer is not correct.
Because she should have expressed 17 as (10+7), then if she multiplied (438 by 10) and (438 by 7). And, then added the results.Then her answer would be correct.
