Anit [1.1K]

Answer and explanation:

Since a quarter(1/4) of paint covers 80 square feet, a whole paint would cover 80×4= 320 square feet of the wall

Remaining part of the wall left unpainted after using one whole paint

480-320= 160 square feet

Therefore paint required for remaining unpainted part

= 160/80= 2 quarters of paint(1/4+1/4)= 1/2 paint

Total paint required for the wall = one whole paint + half paint = 1+1/2= 1 1/2

Total paint required is one and half

Or

We divide area of wall by area of wall covered by each quarter

480/80=6 quarters of paint

6 quarters of paint = 1/4+1/4+1/4+1/4+1/4+1/4

We still get same answer

= 1 1/2

Simplify (x - square root 7)^2
svetoff [14.1K]

Answer:

x^2 + -2 sqrt(7) x + 7

Step-by-step explanation:

Expand the following:

(x - sqrt(7))^2

(x - sqrt(7)) (x - sqrt(7)) = (x) (x) + (x) (-sqrt(7)) + (-sqrt(7)) (x) + (-sqrt(7)) (-sqrt(7)):

x x - sqrt(7) x - sqrt(7) x - (-sqrt(7) sqrt(7))

(-1)^2 = 1:

x x - sqrt(7) x - sqrt(7) x + (sqrt(7))^2

x x = x^2:

x^2 - sqrt(7) x - sqrt(7) x + sqrt(7)^2

Cancel exponents. (sqrt(7))^2 = 7:

x^2 - sqrt(7) x - sqrt(7) x + 7

Combining like terms, sqrt(7) x (-1) + sqrt(7) x (-1) = -2 sqrt(7) x:

Answer:  x^2 + -2 sqrt(7) x + 7

A line passes through (10,4) and (13,-11). Write the equation of the line in standard form.
AlexFokin [52]

\bf (\stackrel{x_1}{10}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{13}~,~\stackrel{y_2}{-11}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-11-4}{13-10}\implies \cfrac{-15}{3}\implies -5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-4=-5(x-10)


now

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

therefore,


\bf y-4=-5(x-10)\implies y-4=-5x+50\implies \blacktriangleright 5x+y=54 \blacktriangleleft
