Answer:

53/8

Step-by-step explanation:

16\frac{7}{8} -10\frac{1}{4}

convert to improper fractions

\frac{7+16*8}{8} -\frac{1+10*4}{4}=\frac{135}{8} -\frac{41}{4}

the common denominator is 8, so multiply the second fraction by \frac{2}{2}.

\frac{135}{8} -\frac{41*2}{4*2}=\frac{135}{8} -\frac{82}{8}

subtract

\frac{135}{8} -\frac{82}{8}=\frac{135-82}{8}=\frac{53}{8}

A regular chicken pen is 4 times as long as it is wide. If the area of the pen needs to be 144 square feet, hot much fencing is
dalvyx [7]

Answer:

60

Step-by-step explanation:

Length=4w

Width=w

Area=length×width

144= 4w × w

4w²=144( Divide both sides by 4)

w²=36

w²-36=0 (Factorise the Quadratic Equation)

(w+6)(w-6)=0

(w+6)=0 or (w-6)=0

w= -6 or w=6

Since length can't be a negative value,

w=6

4w=6×4=24

Perimeter= 6+6+24+24=60

(-m^2+6)+(-4m^2+7m+2)​
marta [7]

Answer:

-5m^2+7m+8

Step-by-step explanation:

We are given the equations

(-m^2+6)+(-4m^2+7+2)

We need to combine like terms. As there are no exponents or numbers outside the parenthesis, we can just drop them and add all like terms

-m^2+6-4m^2+7m+2\\\\-5m^2+7m+8
