(Im bad at explaining but that is right trust me :P)
Step-by-step explanation:
Answer:the last box
Step-by-step explanation:the other ones wouldnt make any sense
Sheila Total:: 6x
<span>Sherri Total:: 5(x+10) = 5x+50
</span><span>(a) Write an equation. Let x represent the amount of one of Sheila’s deposits.
6x = 5x+50
</span><span>(b) Solve the equation. Show your work.
x = 50
</span><span>(c) Check your solution. Show your work.
6*50 = 5(50+10)
300 = 5*60
300 = 300</span>
<span>(d) State the solution in complete sentences.
I'll leave that to you.

The answer is 64+8y+y².
In a perfect square trinomial, you can divide the value of b by 2 and square it, and it will equal the value of c. This works in every other trinomial listed except this one:
8/2 = 4; 4²=16≠64.
