Bryan has 180 feet of fencing. he use the wall for one side of fencing

So he has to fence only 3 sides

he has to fence bottom side + left side+  right side of the wall

Let x be the width of the garden

Let y be the length

Perimeter of the garden = length + width + width

180 = y +x +x

180 = y+2x

so y = 180 - 2x

(a) Area of rectangle = Length * width

Area = y * x

Area = (180 -2x)* x

so area of the garden = -2x^2 +180x

(b)To find dimension to create largest are we find x coordinate of the vertex

formula is x= \frac{-b}{2a}

a= -2 and b = +180

x= \frac{-180}{2(-2)}= 45

So width = 45

We know length y = 180 - 2x= 180 - 2(45) = 90

Dimension with greatest area is

Length = 90 feet

width = 45 feet

(c) Greatest area = length * width

= 90 * 45 = 4050 square feet

45x+10y+50=?<br> PLZ HELP ASAP DUE TODAY!
Viktor [21]

Answer:

5(9x + 2y + 10)

or

x = 0

y = -5

Step-by-step explanation:

If you are just factoring this, you will factor a 5 out from everything.

5(9x + 2y + 10)

or if you are trying to solve just isolate one of the variables and then substitute it into the original equation

45x + 10y = 50

10y = 50 - 45x

y = 5 - 4.5x

45x + 10(5-4.5x) + 50

45x + 50 - 45x + 50

x=0

45(0) + 10y + 50

0 + 10y + 50

10y + 50

10y = -50

y = -5

and it would be x = 0 and y = -5

1, 3, 9, 419, 1257, 3771
Factors of 3298 are:
1, 2, 17, 34, 97, 194, 1649, 3298

As you can see, no factors goes into both number.
Therefore, there should be no number goes into both 3771 and 3298 evenly. 

Hope this helps and hope I didn't misunderstood this question. :D

If cade shoots 275 free throw baskets in 2 hours, how many can he shoot in 5 hours
Volgvan
Hey there! :D

Find the unit rate. 

275/2= 137.5 

Cade shoots 137.5 free throws per hour. Multiply that by 5 for 5 hours. 

5*137.5= 687.5 

He can shoot 687.5 free throws in one hour. You could just round that to 688.

I hope this helps!
