1. How can you prove that a line parallel to one side of a triangle divides the other 2 sides proportionally?

2. In an isosceles triangle, how do you prove the base angles are congruent?

Answer:

the second one

Step-by-step explanation:

if the two given angles are the same, that means there is the same distance between their lines.

cbd is one angle, being shared by both of the points in the answer, does this make sense?

Answer:

I think it's 4.52.  Only if that's one of the options I guess. Good luck!

Answer:

(25/4)∏   or (6 1/4)∏

Step-by-step explanation:

Answer:

Let's simplify step-by-step.

3x2+9x+6−(8x2+3x−10)+(2x+4)(3x−7)

Distribute:

=3x2+9x+6+−8x2+−3x+10+(2x)(3x)+(2x)(−7)+(4)(3x)+(4)(−7)

=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28

Combine Like Terms:

=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28

=(3x2+−8x2+6x2)+(9x+−3x+−14x+12x)+(6+10+−28)

=x2+4x+−12

Answer:

B.) Associative Property of Addition

Step-by-step explanation:

This is because none of the numbers change places the only things that move are the parenthesis which correspond with the associative property.

Answer:

3.14 times 0.10. comes out to be 31.4 .

Step-by-step explanation:

Answer:

Step-by-step explanation:

The surface area of a sphere (which the earth is considered to be) = 4 pi r^2

pi = 3.14

r = 6340

Area = 4 * 3.14 * 6340 * 6340 = 504856736 square km.

You should either round this to 505,000,000 or express a value in scientific notation.

5.05 * 10^8

Answer:

Add 3. Double that. Subtract 4. Cut that in half. Subtract your original number. Your result is 1!

Step-by-step explanation:

I'm guessing, Hope its right.

Answer:

b=7

Step-by-step explanation:

Plug 3 into a since a=3.

2(3)+b=13

Then solve for 2(3)

6+b=13

Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)

b=13-6

b=7

Answer:

3⅞ is the answer to the question.

Step-by-step explanation:

The ten lightest tomatoes are in ¼, ⅜, ½, ⅝ and ⅞.

In ¼, there are 3 tomatoes, so that would be “¼×3=¾”.

In ⅜, there are 2 tomatoes, so that would be “⅜×2=¾”.

In ½, there are 3 tomatoes, so it would be “½×3=3/2”.

In ⅝, there is 1 tomato, so it would be “⅝×1=⅝”.

In ⅞, there is 1 tomato, so that would be “⅞×1=⅞”.

Now add all together:

¾ + ¾ + 3/2 + ⅝ + ⅞

= 5+5+7+6+8/8

= 31/8

= 3⅞

Answer:2/3

Step-by-step explanation The fractions 2/3 and 2/5 have the same numerator. The denominator 3 in the fraction 2/3 means that the unit has less parts, making the parts larger. Therefore, 2/3 is larger than 2/5 . The larger the denominator the smaller the fraction.

Answer:

The answer will be 0.666 repeating.

Step-by-step explanation:

4/6 = 0.6666.....

Since the numerator (4) is smalled than the denominator(6) the answer will be a decimal.

when 4 is divided by 6 it will gives us 0.66666667....

Hope this helps!! I guess

Answer:

The fraction 4/6

has decimal expansion 0.6667

0.6667

(rounded) which means 66.67

66.67

or it can be 2/3

Step-by-step explanation:

Answer:

y = -2/3 x + 25/3

Step-by-step explanation:

The slope = (y_2 - y_1) / (x_2 - x_1) = (9 - 7) / (-1 - 2) = -2/3.

Our equation needs to be in y = mx + b form.

We can plug in (2, 7) as our (x, y) and find b:

7 = -2/3 (2) + b

b = 7 + 4/3 = 25 / 3.

Therefore, our equation is y = -2/3 x + 25/3

Use the Equation(in the picture) and plug in your variables to find m(slope)

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ - 11}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{85 + ( - 96)}[/tex]

Multiplying positive integer and negative integer gives a negative integer i.e ( + ) × ( - ) = ( - )

[tex] \longrightarrow{ \sf{85 - 96}}[/tex]

The negative and positive integers are always subtracted but posses the sign of the bigger integer

[tex] \longrightarrow{ \sf{ - 11}}[/tex]

Hope I helped!
