How do you solve these problems without numbers

1 answer:

i dont know if you want me to answer them or not, but you have to COMBINE LIKE TERMS if you dont then your problems would be messed up example if you have a+a it would be 2a make sense? so you want everything combined then you have to solve. theres no possible way of solving these without numbers number would have to be added although youll probably end up getting rid of the numbers in the end. after you combine like terms do the rest of solving

hope that helps if you need more help pm me, :)

A rectangle has a height of 3n^2 and a width of 4n^2-5n-1.

Galina-37 [17]

Answer:

$A = 12n^4-15n^3-3n^2$

Step-by-step explanation:

The dimensions of a rectangle are length and breadth/width

Here we are given height . Assuming it to be one of the side of the rectangle , we will do the further calculation

Hence one side is

side 1 = $3n^2$

And the other side is

Side 2 = $4n^2-5n-1$

The area of rectangle = side 1 x side 2

$A=3n^2 \times (4n^2-5n-1)$

$A=3n^2 \times 4n^2-3n^2 \times 5n-3n^2 \times 1$

$A=3 \times 4 \times n^2 \times n^2- 3 \times 5 \times n^2 \times n - 3n^2$

$A = 12n^4-15n^3-3n^2$

Hence area can be given as expression

$A = 12n^4-15n^3-3n^2$

A motel clerk counts his $1 and $10 bills at the end of the day. He finds that he has a total of 55 bills having a combined mo

vfiekz [6]

Answer

39 bills of 1$

16 bills of 10$

Step-by-step explanation:

x-nr of $1

y-nr of $10

x*1+y*10=199

x+y=55 , x=55-y

so I use the substitution method

(55-y)*1+10y=199

55+10y-y=199

-55 -55

9y=144

y=144/9

y=16

so x=55-16

x=39

verify 16*10+39*1=160+39=199
