Vaughn pang sketched trapezoid ruiz on a coordinate plane. ruiz has vertices located at r 1,4), u(-2,0), (7,0), and z(3,4). which of the following is the perimeter of ruiz?

To determine the perimeter of the trapezoid, we just have to determine the distance between the pair of points which can be calculated through the equation,
                                  d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting,
     (1,4) and (-2,0)        d = √(1 - -2)² + (4 - 0)² = 5
     (-2,0) and (7,0)        d= √(-2 - 7)² + (0 - 0)² = 9
     (7,0) and (3,4)         d = √(7 - 3)² + (0 - 4)² = 5.66
    (3,4) and (1,4)          d = √(3 - 1)² + (0 - 0)² = 2

The perimeter is the sum of the distances. Thus, the answer is 21.66. 

yes

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
