Answer:

  Prove the lengths are the same

Step-by-step explanation:

When we say segments are congruent, we mean their lengths are the same.

__

Let's see if they are congruent.

  AD = √((3-(-3))² +(2-2)²) = 6

  BC = √((6-0)² +(6-6)²) = 6

AD ≅ BC . . . . their lengths are the same

Solve the following quadratic equation 6x2 – 7x = 20
siniylev [52]

Answer:

<h2>x = 5/2 , x = - 4/3</h2>

Step-by-step explanation:

6x² - 7x - 20 = 0

Using method of factorization

Rewrite - 7x as a difference

That's

6x² + 8x - 15x - 20 = 0

Factor the expression

That's

2x( 3x + 4) - 5( 3x + 4) = 0

Which is

(2x - 5) (3x + 4) = 0

2x - 5 = 0

2x = 5

Divide both sides by 2

x = 5/2

3x + 4 = 0

3x = - 4

Divide both sides by 3

x = -4/3

Hope this helps you

Determine the intercepts of the line.
Ymorist [56]

Step-by-step explanation:

The x-intercept is the value of x when y is 0

So you need to substitute:

0 = 4x + 7

-7 = 4x

-7/4 = x

(-7/4,0)

Similarly, the y-intercept is the value of y when x is 0

So:

y = 4x + 7

y = 4(0) + 7

y = 7

A submarine descends 45 1/2 feet from the ocean surface, clinbs 39 ft, and then descends an additional 18 3/4 ft. What must the
tekilochka [14]
The answer is fill its tanks with air so it floats to the top, but I will solve for the distance since I am nice

so we do
decent means negative
cimb=positive
add

decends 45 and 1/2
-45 and 1/2

climbs 39
+39

decedns 18 and 3/4
-18 and 3/4

add
-45 and 1/2+39-18 and 3/4
add
convert 1/2 to 2/4
gropu negatives
-45 and 2/4-18 and 3/4+39
add
-63 and 5/4+39
-64 and 1/4+39
-25 and 1/4
that is how far dow the submarine is
so the submarine needs to gu 25 and 1/4 ft up to reach the csurface
