Defining congruent triangles

1 answer:

seropon [69]3 years ago

5 0

Answer:

E -->R

D-->K

O-->O

Step-by-step explanation:

Assuming you are asking for congruent parts, correspondence is the part which corresponds and is also equal.

Here Angle E corresponds and is congruent to Angle R in these congruent triangles.

Angle D is congruent and corresponds to Angle K for these congruent triangles.

Angle O is equal to Angle O as they are vertical angles across a vertex.

H(y)=9/5 • 2y at y=-2

Deffense [45]

Answer:

$H( - 2) = - 7 \frac{1}{5}$

Step-by-step explanation:

We want to evaluate the equation

$H(y) = \frac{9}{5} \times 2y$

at y=-2

We just have to substitute to obtain;

$H( - 2) = \frac{9}{5} \times 2 \times - 2$

We now multiply to get:

$H( - 2) = \frac{9}{5} \times - 4$

This is the same as:

$H( - 2) = \frac{9}{5} \times \frac{ - 4}{1}$

We multiply the numerators separately and denominators separately to get:

$H( - 2) = \frac{9 \times - 4}{5 \times 1}$

$H( - 2) = \frac{ - 36}{5}$

This implies that

$H( - 2) = - 7 \frac{1}{5}$

F(x)=(x+7)^3 expand the function

nydimaria [60]

Step-by-step explanation:

F(x) = (x + 7)³

= 3C0 * x³ + 3C1 * x² * 7 + 3C2 * x * 7² + 3C3 * 7³

= x³ + 21x² + 147x + 343.

I'm not sure what this means, please help me I'll give you 10 points ;)

<u>Answer:</u>

So all the possible solutions are:

$\bold{523,~400,~379~and,~378.6}$

<u />

<u>Solution Steps:</u>

<em>First you need to solve the real inequality to understand how to find the rest of the possible equations. </em>

<u>Add 78 to both sides:</u>

<u /> $78+78=$ Cancels Out

$300+78=378$

<em>So now we know the real answer, but it ask for all possible answers. </em>

(Means anything larger than 300 when you plug it into x - 78 > 300.)

<u>Numbers that are greater than 378:</u>

1.) $377-78=299 > 300$ (False)

2.) $523-78=445>300$ (True)

3.) $0-78=-78>300$ (False)

4.) $-62-78=-140>300$ (False)

5.) $400-78=322>300$ (True)

6.) $379-78=301>300$ (True)

7.) $222-78=144>300$ (False)

8.) $378.6-78=300.6>300$ (True)

dimaraw [331]

Answer:

$\sqrt{2^5}$

Step-by-step explanation:

$2^{1/2}$ × $2^{3/4}$ = $2^{5/4}$

( $2^{5/4}$ )² = $2^{5/2}$ = $\sqrt{2^5}$
