Recognizing the Steps Vx
To model the problem containing an unknown number, translate the statement into an equation.
Sixteen is five less than a number.
Which steps would you take to translate the statement?
O Replace "is” with = "less than" with –, and "a number" with n to get 16 = 5-n.
O Replace "is" with =, "less than" with +, and "a number with n to get 16 = n +5.
O Replace 'is” with =, "less than" with –, and "a number" with n to get 16 = n -5.
O Replace "is” with =, "less than" with –, and a number” with n to get 16 = 5 :n.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
