Answer:
1) distributive property.
Step-by-step explanation:
Becca used the distributive property, in that she distributed (multiplied) 4 to all terms within the parenthesis:
4(x + 2) = 4x + 8

Answer:
16 cm
Step-by-step explanation:
Let the width be x
The length will be 3 x since the length is three times the width
Perimeter=2(l+w) where l is length and w is width
By substituting 128 cm for perimeter, x for w and 3 x for l then
128=2(3x+x)
128=8x

Therefore, the width is 16 cm, the width is 16*3=48 cm
If the interst rate is 2% per year and she paid it back after 3 years , it means she paid an extra 6% of $2000 just in interests.
Now we just need to find how much 6% is and add to 2000.
to discover the value of 6% of 2000 we can divide it by 100 ( to find 1%) and then multiply it by 6 ( to find 6%) :
2000 ÷ 100 = 20
1% = 20
6% = 20 × 6
6% = 120
Now add 120 to 2000 to find out how much she paid in total:
2000 + 120 = 2120
Awnser : She paid the total of $2120 over 3 years
I hope you understood my brief explanation. And please consider marking this awnser as Branliest. Thank you ! :)
<span> 1 .Convert the 2/5 to decimal, or 0.4
the percentage is now 41.4%
2. convert the percentage to decimal by dividing by 100:
41.4%/100 = 0.414
answer is 414/1000 simplify 207/500 </span>
V=πr²h
1000=πr²(8)
r²=39.79
r=6.3
Hope this Helps! :D
