Iteru [2.4K]4 years ago

The perimeter of a polygon is the sum of the lengths of all its sides. A rectangle has 4 sides, and opposite sides are congruent, so 2 sides have length x + 5, and 2 sides have length 11. Add all the lengths and set the sum equal to 50. Then solve the equation for x.

x + 5 + x + 5 + 11 + 11 = 50

2x + 32 = 50

2x = 18

x = 9

Answer: x = 9

If f(x)=-2x-3 what is f(r+2) ?
fiasKO [112]

Answer:

f(x) =  - 2x - 3

when x is r + 2 :

f(r + 2) =  - 2(r + 2) - 3 \\  =  - 2r - 4 - 3 \\  =  - 2r - 7 \\  \\ { \boxed{ \boxed{f(r + 2) =  - 2r - 7}}}

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought
Klio2033 [76]
He bought 4 books.  

3.95m + 8.95b = 47.65

If he bought 3 magazines, m =3
(3.95)3 +8.95b = 47.65
11.85 + 8.95b =47.65
now we subtract 11.85 from both sides
8.95b = 35.80
we divide both sides by 8.95
b=4
Hugh bought 4 books.

gulaghasi [49]

Answer:

The easiest ways to do this is to add, subtract, multiply, or devide 5 from a number, do that operation to x, and set that number as the equivelent.

For example

3 * 5=15

so

3x=15
