1. 160 2. 520 3.240 hopefully they are right
True multiply both sides by 15
Answer: 8y4+25y3+60y2+10y+7
Step-by-step explanation:
(y2+3y+7)(8y2+y+1)
=(y2+3y+7)(8y2+y+1)
=(y2)(8y2)+(y2)(y)+(y2)(1)+(3y)(8y2)+(3y)(y)+(3y)(1)+(7)(8y2)+(7)(y)+(7)(1)
=8y4+y3+y2+24y3+3y2+3y+56y2+7y+7
=8y4+25y3+60y2+10y+7
hope this helps!:)
1. 5^2 = 25
2. 2^6 = 64
3. 25^(1/2) =5
2 x 230 = 231
I’m not 100% sure if this is correct?? Hope it helps though
