Step-by-step explanation:
let the number be x
12x-59=x²-2
12x-x²=59-2
12x-x²=57
12x-57=x²
x=root of 12x-57
Answer:
c < - 4
Step-by-step explanation:
- 4c - 1 > 15 ( add 1 to both sides )
- 4c > 16

c < - 4
Answer:
The answer choice you should pick is n = 1/5.
Answer:
143cm
Step-by-step explanation:
Area=2(l+b)
Substitute the values for the variables.
66=2(l+22/5)
66=2xl+2x<u>22</u>
5
66=2l+<u>44</u>
5
Cross multiply
66x5=2l+44
330=2l+44
Collect like terms
-2l = 44-330
-2l = -286
<u>-2l </u>=<u> </u><u>-286</u>
-2 -2
l=143
The missing length is 143m.
Answer: The one on the right. Each side is multiplied by 6, therefore they are similar.
