WILL MARK BRAINLIEST AND 20 POINTS Determine algebraically whether each of the following functions is even, odd, or neither. f(x

Alex787 [66]

Answer:

Neither

Step-by-step explanation:

The function is neither because if it was even it would follow the rules of:

$f(-x)=f(x)$

and if it was odd it would follow the rules of:

$-f(x)=f(-x)$

but instead it follows the rule:

$-f(x)\neq f(-x))\\$

Are triangles DEF and LNM similar if LN equals 5 MN equals 3 DE equals 10 and FE equals 6

melisa1 [442]

Answer:

D. Yes by SAS Similarity Postulate

Step-by-step explanation:

This is the answer because if you flip triangle LNM around to shape the DEF. Then you will see that:

1. angle D is congruent to angle L

2. angle E is congruent to angle N

3. angle F is congruent to angle M

4. angle E and N are both 90 degrees

Because (DE and LN) and (MN and FE) are similar and (E and N) are 90 degrees, then we do not need (FD and ML) to tell if triangle DEF and triangle LNM is similar or not. They are similar.

We next need to figure out if the triangles are similar by SSS (Side-side-side) Similarity Postulate or SAS (side-angle-side) Similarity Postulate. The SAS Similarity Postulate states that if you have 2 similar sides and 1 congruent angle, then the two shapes are similar. Right now we have 2 similar sides in (DE and LN) and (MN and FE) and 1 congruent angle that are both 90 degrees. This follows all the rules of the SAS Similarity Postulate, so that means that these two triangles are similar by SAS Similarity Postulate.

What is the answer to <br> x=3x-20 and y=-6+30

NISA [10]

Answer:y=24 and x=10

Step-by-step explanation:

To find the value of x and y in x=3x-20 and y=-6+30

We gets

y=24

To get x

x=3x-20

Collect like terms

x-3x=-20

Divide through by -2

-2x=-20

x=10

Find the area of ABC<br>Help

Katarina [22]

The value of the scale factor is 3. Then the height and area of the triangle ΔABC will be 9 ft and 54 square ft.

<h3>What is dilation?</h3>

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

The area of the triangle ΔDEF is 6 square ft. And the base length of the triangle ΔDEF is 4 ft.

The area of the triangle is given as

$\rm Area = \dfrac{1}{2} \times bh\\\\$

Then the height of the triangle ΔDEF will be

$\rm 6 = \dfrac{1}{2} \times 4 \times h\\\\h = \dfrac{12}{4}\\\\h = 3$

Then the scale factor will be

$\rm SF = \dfrac{12}{4} = 3$

Then the height of the triangle ΔABC will be

$\rm \dfrac{H}{3} = 3\\\\H \ = 9$

Then the area of the dilated triangle ΔABC will be

$\rm Dilated \ Area = \dfrac{1}{2} \times 12 \times 9\\\\Dilated \ Area = 54 \ ft^2$

More about the dilation link is given below.

36x^3a+45xa^2=9xa( ) complete the statement.

Dafna1 [17]

9xa is the common factor.

You can complete the statement by dividing the two terms of the expression of the left side by 9xa, and you will get:

36x^3a + 45xa^2 = 9xa ( 4x^2 + 5a)
