Answer:
(-3 , -3)
Step-by-step explanation:
A: (-1,2), B: (1,2), and C: (-1,-3) .... D: (x,y)
slope of AB = (2-2)/(1 - -1) = 0 .... parallel to x axis
x coordinate of A is 2 units left to B (-1 vs 1)
y coordinate of C is 2 units left to B so D must be 2 units left to C: -1 -2 = <u>-3</u>
DC // AB , y coordinate of D = C =<u> -3</u>
D: (-3 , -3)

you convert them all to decimal and arrange them in order.
A rectangle is a quadrilateral and its area is expressed as the product of its length and width. From the given, we have:
Length = x + 2
Width = 2x - 5
Area = 54 cm^2
Area = Length x Width
Substituting the values,
Area = (x + 2) ( 2x-5) = 54
54 = 2x^2 - x - 10
2x^2 - x - 64 = 0
We can see that the equation above is a polynomial with a degree of 2 therefore we can usethe Quadratic Formula to solve for x. The quadratic formula will solve two values of x.
x1 = (-b + (√b^2 - (4ac))/ 2a = 5.91
x2 = <span>(-b - (√b^2 - (4ac))/ 2a = -5.41
Since, for this case, the value x should not result to a negative value for both dimensions thus x is equal to 5.91.</span>

Answer:
C = 288 kg
Step-by-step explanation:
Given:
C = 72m^2/4
where,
C = approximate number of calories
m = animal mass in kilograms.
Find C when m = 16
C = 72m^2/4
= 72 * (16)^2/4
= 72 * (16)^1/2
= 72 * √16
= 72 * 4
= 288
C = 288 kg
