Answer:

A quadrilateral is defined as a polygon which has 4 sides, that's it. If the quadrilateral has equal angles or equal sides is not the matter, the definition is just about the number of sides.

So, if Sheena claims that all quadrilaterals are rectangles, she is completely wrong, because to a quadrilateral become a rectangle, opposite sides have to be congruent and parallel, also angles must be equal to 90°, and these elements is not derived from the definition of a quadrilateral.

Therefore, quadrilaterals' definition is too general to make the claim Sheena is doing.

Quadrilaterals are shapes that have 4 sides.So it's not only rectangles.

Answer:

C=0.65M+22.65

Step-by-step explanation:

The standard charge includes an initial fee and plus an addditional fee for each mile driven and is given by:

S=0.40M+17.75

The insurance charge is given by:

I=0.25M+4.90

So, the total charge C will be the sum of the standard charge S and the insurance charge I:

C=S+I

Substitute:

C=(0.40M+17.75)+(0.25M+4.90)

Rearrange:

C=(0.40M+0.25M)+(17.75+4.90)

Add:

C=0.65M+22.65

And we have acauired our equation relating C to M!

Three different ways to put 6(3x + 8) + 32 + 12x
Sever21 [200]

Answer:

<em>Writing 6(3x + 8) + 32 + 12x in 3 different ways:</em>

  • w₁ = 18x + 48 + 32 + 12x      

∵ 6(3x + 8) = 18x +48 as distribute law suggests that  a(b + c) = ab + ac

  • w₂ = 18x + 80 + 12x              ∵ 48 + 32 = 80
  • w₂ = 30x + 80                        ∵ 18x + 12x = 30x

Step-by-step explanation:

As the expression is 6(3x + 8) + 32 + 12x, and we have to write it in three different ways. Using the properties of operations we can write it in three different ways,

Let way one be denoted as w₁

Let way two be denoted as w₂

Let way three be denoted as w₃

So, lets write 6(3x + 8) + 32 + 12x in 3 different ways:

  • w₁ = 18x + 48 + 32 + 12x      

∵ 6(3x + 8) = 18x +48 as distribute law suggests that  a(b + c) = ab + ac

  • w₂ = 18x + 80 + 12x              ∵ 48 + 32 = 80
  • w₂ = 30x + 80                        ∵ 18x + 12x = 30x
