Answer:
$13.68
Step-by-step explanation:
An easy way to find 3/8 of $36.48 is to find 1/8 first. To do this divide 36.48 by 8. This equals 4.56, then to find 3/8 multiply this by 3. Which equals $13.68. A faster way to do this is also to just multiply 3/8*36.48, which also equals $13.68.
For the first one is a for the second one is b for the third one is c for the fourth one is d that’s all the answer
If xy=0 assume that x and y=0
so
(2x-8)(7x+5)=0
assume
2x-8=0 and 7x+5=0
solve each
2x-8=0
2x=8
x=4
7x+5=0
7x=-5
x=-5/7
so x=-5/7 or 4
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!:)
