B2+20b+100 polynomial answer

try (b+10)^2

Step-by-step explanation:

Step 1: Rewrite

b^2+20b+100 > b^2+(2b*10)+10^2

Step 2: Apply square formula (a+b)^2 = a^2+2ab+b^2

b^2+(2b*10)+10^2 > (b+10)^2

Hope this helps!

i think it might be a but you might want a second opinion

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
