Patty can make 10 purses in 8 hours. At this rate, how many purses can she make in 28 hours? ​
djverab [1.8K]

Answer:

35 purses

Step-by-step explanation:

Set up a proportion, where x is the number of purses she can make in 28 hours:

\frac{10}{8} = \frac{x}{28}

Cross multiply and solve for x:

8x = 280

x = 35

So, in 28 hours, she can make 35 purses

(c+d)^2+11(c+d)+30<br><br> Factor completely.
tatyana61 [14]

Answer:

firstable give c+b a polynomial value like x

so its will be x^2+11x+30

after the we have to factor it

30=6×5

and 11=6+5

so its will become

(x+6)×(x+5)=x^2+11x+30

x=c+d

(c+d+6)×(c+d+5)=(c+d)^2+11(c+d)+30

have a great day
