if n represent number than write an expression for three times the difference of the number amd six increased by four times the
lorasvet [3.4K]

Let n be the number. The difference of the number and six is n-6. Then three times the difference of the number and six is 3·(n-6). This number 3·(n-6) increased by four times the number n, then

3·(n-6)=4·n.

Solve it:

3·n-3·6=4n,

3n-4n=18,

-n=18,

n=-18.

Answer: n=-18 and expression is 3·(n-6)=4·n.

strojnjashka [21]
X² + 18x + 79 = 0
x = <u>-(18) +/- √((18)² - 4(1)(79))</u>
                       2(1)
x = <u>-18 +/- √(324 - 316)</u>
                     2
x = <u>-18 +/- √(8)
</u>              2<u>
</u>x = <u>-18 +/- 2√(2)
</u>               2<u>
<em /></u><em />x = -9 <u>+</u> √(2)
x = -9 + √(2)      x = -9 - √(2)
