$\sqrt{126}= 3\sqrt{14} \\ \\ \sqrt{56}=2\sqrt{14} \\ \\ \\ \sqrt{126}+ \sqrt{56}= 3\sqrt{14}+2\sqrt{14}= 5\sqrt{14}$

$\sqrt{126}+\sqrt{56}=\sqrt{9\times14}+\sqrt{4\times14}=\sqrt9\times\sqrt{14}+\sqrt4\times\sqrt{14}\\\\=3\sqrt{14}+2\sqrt{14}=5\sqrt{14}$

the amount of food a dog should eat depends on the weight of the dog. 1. identify the independent and dependent variables in thi

fomenos

Here, we are required to identify the dependent and independent variables, the dependency relationship in the situation.

The independent and dependent variables are the weight of the dog and the amount of food it should respectively.
The dependency relationship is thus; The amount of food a dog should eat is a function of the weight of the dog
The dependency relationship using the function notation is; f(x) = {function of x}.

The independent variable in this situation is the weight of the dog while the amount of food the dog should eat is the dependent variable. The above is evident from the statement; The amount of food a dog should eat depends on the weight of the dog.

According to the premise given in the question, it is evident that the dependency relationship is;. The amount of food a dog should eat is a function of the weight of the dog

The dependency relationship can be written mathematically using the function notation as;. f(x) = {function of x}.

The length of a rectangle is four times its width. If the area is 400 cm squared, find its perimeter

Tasya [4]

A = L * W
A = 400
L = 4W

400 = 4W * W
400 = 4W^2
400/4 = W^2
100 = W^2
sqrt 100 = W
10 = W.....width is 10 cm

L = 4W
L = 4(10)
L = 40...length is 40 cm

P = 2(L + W)
P = 2(10 + 40)
P = 2(50)
P = 100 <=== perimeter is 100 cm

Step-by-step explanation:

7. ∆ABC = ∆ILH by SSS

as, AB = IL , BC = LH , CA = HI

8. ∆DEF = ∆AMS by ASA

as , angle D = angle A, EF = MS , angle F = Angle S

9. ∆JKL = ∆HAT by SAS

as, JK = HA , KL = AT , angle L = angle T

10. ∆ABC = ∆KPG by ASA

as , CA = GK, Angle c = angle G and Angle B = angle P

11. ∆ABC = ∆YDE by ASA

as , angle A = angle Y, AB = YD , angle B = angle D

12. ∆MNO = ∆SAK by ASA

as , Angle M = angle S, NO = AK, angle O = angle K

hope this answer helps you dear...and may u have a great day ahead!
