Answer:

Step-by-step explanation:

i = $\sqrt{-1}$

$\sqrt{125}$ is equal to 5 $\sqrt{5}$

Since it is $\sqrt{-125}$ , then you must have i as well

5i $\sqrt{5}$

please give a heart to give thanks :)

a crown would be nice too :)

- the type of pair is vertical angle.

- to find x:

-- vertical angles are equal.

4x + 10 = 5x - 1

10 = x - 1

x = 11

The zeros of a parabola are –4 and 2, and (6, 10) is a point on the graph. Which equation can be solved to determine the value o

Oliga [24]

The equation of the parabola is
.. y = a(x +4)(x -2)

Substituting (x, y) = (6, 10) gives
.. 10 = a(6 +4)(6 -2)

The 4th selection is appropriate.

15 less than a number S is three more than 9 times a number T. Solve for S

lbvjy [14]

Answer:

s = 9t + 18

Explanation:

Set up your equation

s - 15 = 9t + 3

Now get s by itself by adding 15 to both sides

s + 0 = 9t + 3 + 15

s = 9t + 18

If you know the value of t, plug that into the equation to solve further.

ASAP HELP! Look how much im offering, congruent shapes.

Answer:

D. 7.5 inches

Step-by-step explanation:

So, we can find the ratio of the big triangle to the small one by dividing the values of the hypotenuse.

So, 18/6 = 3

Big:small = 3:1

So, using this we can make an equation to find AD.

Let's say ED=x.

AD is basically ED (x) + AE (5).

Since ED is part of the small triangle, and AD is part of the big one, we can use the 3:1 ratio from above.

So, $\frac{x+5}{x}$ =3.

Multiply both sides by x, getting x+5 = 3x.

Subtract the x: -x -x

And you get 5=2x, giving you 2.5 = x.

However, we're not done yet, as 2.5 is the value of ED, but we need AD.

Remember, AD is = ED + AE.

So, AD = 2.5 + 5.

Finally, AD = 7.5
