In The Diagram Below Of Triangle BCD, E Is A Midpoint Of BC And F Is A Midpoint Of CD. If EF = 44 - 8x,

Answers

Answer 1

Answer:

BD = 24

Step-by-step explanation:

EF = 44 - 8x,

BD = 44 - 5x.

Since EF is a midsegment of ∆BCD, therefore, based on the Midsegment Theorem,

[tex] EF = \frac{1}{2}(BD} [/tex]

[tex] 44 - 8x = \frac{1}{2}(44 - 5x} [/tex]

Multiply both sides by 2

[tex] 2(44 - 8x) = 44 - 5x [/tex]

[tex] 88 - 16x = 44 - 5x [/tex]

Collect like terms

[tex] 88 - 44 = 16x - 5x [/tex]

[tex] 44 = 11x [/tex]

Divide both sides by 11

[tex] 4 = x [/tex]

x = 4

BD = 44 - 5x

Plug in the value of x

BD = 44 - 5(4) = 44 - 20

BD = 24

Step-by-step explanation:

What exactly is your difficulty can you be more specific perhaps?

If I give give you a formulae e.g. N= P¥s/ yR^2 and I don't say what each letter or symbol represents then its meaningless but if I state S = d/t and say that S = speed of an object and that equates to d (distance) divided by t (time) then hopefully you will know and be able to relate to the overall formulae

In my earlier study years I had to learn complex electrical and mechanical formulae e.g. Xl = 2pi f L ( Electrical Inductive Reactance) and its all about finding a strategy that works for you.

You have to get familiar with formulae and thats by practice, the more you use them the more you tend to remember them

4x + 1
20x + 1
4x + 13
20x + 13

Answers

Answer:

Step-by-step explanation:

12x + 6 - 8x + 7

= 12x - 8x + 6 + 7

= 4x + 13

Now multiplication with first part

4x + 1

(4x + 13) * (4x +1)

=4x * (4x +1) + 13 * (4x +1)

=16x^2 + 4x + 52x + 13

=16x^2 + 56x + 13

Now multiplication with second part

20x + 1

(4x + 13) * (20x + 1)

=4x * (20x + 1) + 13 * (20x + 1)

=80x^2 + 4x +260x + 13

=80^2 + 264x + 13

Now multiplication with third part

4x + 13

(4x + 13) * (4x + 13)

=4x * (4x + 13) + 13 * (4x + 13)

=16x^2 + 52x + 52X + 169

=16x^2 + 105x + 169

also equal to

(4x + 13)^2

Now multiplication with fourth part

20x + 13

(4x + 13) * (20x + 13)

=4x * (20x + 13) + 13 * (20x + 13)

=80x^2 + 52x + 260x + 169

=80x^2 + 312x + 169

Step-by-step explanation:

Answer:

27/28

Step-by-step explanation:

To get this answer, you need a common denominator. In this case, a common denominator would be 28. So, you leave 6/28 the same. Now, you need 2 convert 3/4 to 28ths. So, 4 (denominator) times what is 28? Well, 4 times 7 is 28. Whatever you do to the top, you do the bottom. So 3 times 7 is 21. Now, you have an equivalent fraction that is 21/28. Now you can add.

So, 6/28 + 21/28 is equal to 27/28.

40 plus what equals 180

Answers

Answer:

140

Step-by-step explanation:

180 - 40 = 140

reverse operations

140 + 40 = 180

Applying algebra and assuming the unknown value is x, we can determine that 40 plus 140 equals 180.

How to Apply Algebra?

To solve the equation "40 plus what equals 180," we can use algebraic notation. Let's denote the unknown value as "x." The equation can be represented as:

40 + x = 180

To find the value of x, we can isolate it on one side of the equation by performing the same operation on both sides. In this case, we subtract 40 from both sides:

40 + x - 40 = 180 - 40

x = 140

Therefore, 40 plus 140 equals 180.

Sum the 3 angles and equate to 180, that is

6x = 180 ( divide both sides by 6 )

x = 30 → A

Answer:

A) 30

Step-by-step explanation:

The sum of all of the angles in a triangle have to equal 180 degrees.

Plug in 30 for x

3(30) = 90

2(30) = 60

(30)= 30

90+60+30= 180

Therefore x=30 degrees
