3 radical 7 - radical 7
= 3
why is this incorrect?

Answers

Answer 1
Answer:

3√(7) - √(7)

Let x represent √(7), then you can rewrite the expression as 3x - x.

3x - x = 2x.  Now replace "x" with  √(7) and you get 2√(7).

The reason 3 is incorrect is because you are supposed to perform the operation (+, -, x, ÷) with the coefficients, not with the variable or radical.

Answer 2
Answer:

Algebraically, you have to factor the square root of 7 to see why you're wrong:

3√(7)-√(7) = √(7)(3-1) = 2√(7)

Conceptually, think that any object - say an apple - represents the square root of seven.

So, you have three apples, and you take away one apple. You have two apples remaining, i.e. 2√(7)

Quadrilateral ABCD quadrilateral WXYZ. If AD = 12, DC = 6, and ZY = 36, find WZ.

Answers

The value of WZ in the given similar polygons, is 72

What are similar polygons?

When polygons are similar their corresponding angles are congruent and their corresponding sides are proportional.

Given that, quadrilateral ABCD and quadrilateral WXYZ are similar,

The order of the proportionality statement tells us which angles and sides are corresponding.

To solve, set up a proportion.

AD/WZ = DC/ZY

12/WZ = 6/36

Cross multiply.

6(WZ) = 12x36

6(WZ) = 432

Divide both sides by 6

WZ = 72

Hence, the value of WZ is 72
