Ellie wanted to build a fence around her rectangular garden. The garden is 10 ft by 20 ft. A) What is the perimeter of the garden in feet?

Answers

Answer 1

Answer:

60 feet

Step-by-step explanation:

Perimeter is the sum of the four sides of a rectangle

the formula for the perimeter of a rectangle = 2 x (length + breadth)

2 x (10 + 20)

2 x (30)

= 60 feet

Alternatively, you can add the sides together : 10 + 10 + 20 + 20 = 60 feet

Solve the system of equations

2x+3y= 6
x+y=4

(6,-2)
(-2,6)
(-3, 4)
(0, 2)

Answers

Answer:

Step-by-step explanation:

2x+3y= 6     ========================>>>           2x +  3y = 6

x+y=4    =====   times both sides by 2  =====>>>    2x + 2y = 8

             ==== subtract these two equations ==>>  (2x - 2x) + (3y - 2y) = 6 - 8

                                                                                       0x     +      y       =   -2

        y = -2     so if  x + y = 4             plug in -2 where y was

                             x + (-2) = 4              add 2 to both sides

                                    x   =  6

Dvide if the polynomial does not divide evenly. Include the remainder as a fraction (18u^2 - 142u - 11) ÷ (u - 8)​

Answers

Answer:

18u + 2 + 5/(u - 8)

Step-by-step explanation:

(18u^2 - 142u - 11) ÷ (u - 8)​

18u^2 - 142u - 11 = 18u^2 - 8*18u + 2u - 11 = 18u(u - 8) + 2u - 16 + 5 =18u(u - 8) + 2(u - 8) + 5 =(18u + 2)(u - 8) + 5

(18u^2 - 142u - 11) ÷ (u - 8)​  = 18u + 2 + 5/(u - 8)

Answer:

18u + 2 + 5/u - 8.

Step-by-step explanation:

(18u^2 - 142u - 11) ÷ (u - 8)

= 18u + 2 + 5/u - 8.
