Explanation:
Basically triangles are congruent when they have the same shape and size.
Two triangles are congruent if they have :
exactly the same three sides and
exactly the same three angles.
Tips Area :
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent too :)
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent too ;)
If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent too ^^
Hope that help :)
Which products result in a sum or difference of cubes? Check all that apply. (x – 4)(x2 + 4x – 16) (x – 1)(x2 – x + 1) (x – 1)(x2 + x + 1) (x + 1)( + x – 1) (x + 4)(x2 – 4x + 16) (x + 4)(x2 + 4x + 16)
Answer:
(x – 1)(x^2 + x + 1) = x^3 - 1.
(x + 4)(x^2 - 4x + 16) = x^3 + 64.
Step-by-step explanation:

19 is the top and 20 is the bottom what is 19 in a fraction
Answer:
95%
Step-by-step explanation:
you meant what is 19 in a percentage, it means that it is 19/20. So you do 19 divided by 20. Do the math and get .95 ..95=95% .You get this by multiplying te decimal by 100 to find the percentage
Answer:
95%
When it says in percent, just times the fraction by 100
19/20 * 100= 95%
Or ...
You can change it to a decimal and move the decimal point back 2 spaces.
.95 = 95%

what are the solutions to the quadratic equation 9x(2) + 64 = 0?
and
what is the factored form of the quadratic expression 9x(2) + 64?
Answer:
Solution of given quadratic equation is
[tex]$ (\frac{8i}{3}, -\frac{8i}{3} ) $[/tex]
Step-by-step explanation:
The given quadratic equation is
[tex]9x^2 + 64 = 0[/tex]
The general form of the quadratic equation is given by
[tex]ax^2 + bx + c = 0[/tex]
Comparing the general form with the given quadratic equation
[tex]a = 9\\b = 0\\c = 64[/tex]
The solutions of the quadratic equation is given by
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
Substitute the values of a, b and c
[tex]$x=\frac{-0\pm\sqrt{0^2-4(9)(64)}}{2(9)}$[/tex]
[tex]$x=\frac{\pm\sqrt{-2304}}{18}$[/tex]
[tex]$x=\frac{\pm48i}{18}$[/tex]
[tex]$x=\frac{\pm8i}{3}$[/tex]
[tex]$x=\frac{8i}{3}$[/tex]
and
[tex]$x=-\frac{8i}{3}$[/tex]
Where i represents iota which means that the given quadratic equation has complex roots.
So the solution of given quadratic equation is
[tex]$ (\frac{8i}{3}, -\frac{8i}{3} ) $[/tex]
The factored form of the given quadratic equation is
[tex]$ (x+ \frac{8i}{3}) (x- \frac{8i}{3}) = 0 $[/tex]
-5(x+6)=15 what is the answer?? will give brainliest
Answer:
the answer will be x=-9
Step-by-step explanation:
-5(x+6)=15
-5x-30=15
-5x=15+30
-5x=45
×=-9
Answer:
[tex]x=-9[/tex]
Step-by-step explanation:
[tex]-5(x+6)=15[/tex]
Use the distributive property.
[tex]-5x-30=15[/tex]
Add [tex]+30[/tex] on both sides of the equation.
[tex]-5x=15+30[/tex]
[tex]-5x=45[/tex]
Divide [tex]-5[/tex] on both sides of the equation.
[tex]x=45/-5[/tex]
[tex]x=-9[/tex]

Answer:
Measure of the side, x = 5.25 units
Step-by-step explanation:
Figure B is a scale image of figure A.
That means figure B is an image and figure A is a pre-image.
Scale factor for the dilation from figure A to figure B = 1.75
Scale factor = [tex]\frac{\text{Side of image B}}{\text{Side of pre-image A}}[/tex]
1.75 = [tex]\frac{x}{3}[/tex]
x = 1.75 × 3
x = 5.25 units
Therefore, measure of the side figure B is 5.25 units.

mindy opened a bag of skittles and recorded the colors and their frequencies, as shown in the table below. What is the RELATIVE FREQUENCY, rounded to the NEAREST HUNDREDTH, for the number of RED candies?
Answer:
14%
Step-by-step explanation:
first, you would have to find how many skittles there are in total. You would add the red, blue, green, and purple skittles together and get 72. Next you would take the number of red skittles (10) and put it over the number of total skittles (72) and get the fraction 10/72. Lastly divide 10 by 72 and get the decimal .13888889 which would round up to .14 move the decimal over 2 places and get 14%

The altitude to the hypotenuse of a right triangle is the geometric mean between the segments on the hypotenuse.
always
sometimes
never
Answer: always
Step-by-step explanation:
A right triangle is a kind of triangle with one right angle.
Side opposite to right angle is known as hypotenuse.Other two sides is known as legs.A theorem of right triangle says that :-
When the altitude drawn from the right angle to the hypotenuse splits the hypotenuse into two sections of segments. Then the length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.Hence, the statement "The altitude to the hypotenuse of a right triangle is the geometric mean between the segments on the hypotenuse." is always true.
Thus , the correct answer is "always".
Your answer should be always :)

solve for X: 5/6 = 10/2x-3
x=___
Answer:
x = 7.5
Step-by-step explanation:
5/6 = 10/2x-3
Solve using cross products
5 ( 2x-3) = 6*10
Divide each side by 5
2x-3 = 6*10/5
2x-3 =12
Add 3 to each side
2x-3+3 = 12+3
2x =15
Divide each side by 2
2x/2 = 15/2
x = 7.5

Plz help asap. Ahdhduebdhf
Answer:
x = 125
Step-by-step explanation:
all of the angles in a triangle must add up to 180, so 25 + 30 + x = 180. you can subtract 25 and 30 from both sides and you are left with x = 125.
hope it helps!
________________________________
Hey!!!
Solution,
X+30+25=180(Sum of angle in traingle)
or,X+55=180
or,X=180-55
X=125
The value of X is 125.
Hope it helps
