Answer:

-49

Step-by-step explanation:

multiply 7 with 7 then i with i and lastly multiply the result numbers

7i × 7i ➡ 7 × 7 = 49

i × i = i^2

49 × i^2 = 49i^2

i^2 = -1 ➡ 49 × (-1) = -49

25- 20x + 4x^2
=4x^2 - 20x + 25
=4x^2 - x(10+10) +25
=4x^2 - 10x - 10x + 25
=2x(2x - 5) - 5( 2x - 5)
=(2x - 5)(2x - 5)

Answer:

1) B. similar

2) D. (4, 2)

Step-by-step explanation:

When a figure is dilated, the shapes will be similar. Reflected is another transformation so that's wrong. Same size and congruent is wrong since that would have to make the dilated size equal which can't since it's contradicting.

B: (4, -2)

Reflection across the x-axis:

(x, y) → (x, -y)

(4, -2) → (x, -y)

(4, 2)

Is x + 10 a factor of the function f(x) = x3 − 75x + 250? Explain.

lord [1]

Okay, I worked it out and yes, it is a factor. Once you got x=-10, then you plug it into your formula. from there you can work it out like I did and get the answer. You can also input it into a scientific calcuator and figure it out that way. If you need any more help, go ahead and message me. Hope this helps. You can also but it into the box and divide it that way to find out. whichever way is better for you
