To solve, you must use order of operations. The acronym used is BEDMAS (brackets, exponents, division/multiplication, addition/subtraction), which is the order you solve in. 

F  20÷4x5
    =5x5
    =25
      
T   10+10÷2
      =10+5
      =15

F    6+4×5
      =6+20
      =26

<span>T   81÷9+2
     =9+2
     =11</span>

Someone, please help! I'm really confused

The correct pair is option E, which is:

FH ≅ FH - reflexive property

ΔGFH ≅ ΔEFH - SAS theorem

<h3>What is the SAS Congruence Theorem?</h3>

The SAS theorems states that two triangles are congruent if they have two pairs of congruent sides and a pair of congruent included angles.

<h3>What is the Reflexive Property?</h3>

The reflexive property of geometry states that an angle or line will always be congruent to itself.

In the two column-proof, since FH = FH using the reflexive property, then both triangles are congruent to each other by the SAS congruence theorem.

The missing pair of reasons that completes the proof are:

FH ≅ FH - reflexive property

ΔGFH ≅ ΔEFH - SAS theorem

A cylinder's volume can be calculated by the formula V=Bh, where V stands for volume, B stands for base area, and h stands for h
Anastaziya [24]

Answer:

h = 3x^5-3x^2-10\text{ units}

Step-by-step explanation:

We are given the following in the question:

Volume of cylinder =

V=Bh

where B is the area of base and h is the height of cylinder.

Volume of cylinder =

V = 6\pi x^7-6\pi x^4-20\pi x^2

Base area =

B = 2\pi x^2

We have to find height of cylinder.

h = \dfrac{V}{B}\\\\h = \dfrac{6\pi x^7-6\pi x^4-20\pi x^2}{2\pi x^2}\\\\h = 3x^5-3x^2-10\text{ units}

Thus, the height of cylinder is 3x^5-3x^2-10 units.
