10q-30 is equivalent to what ?

butalik [34]

Answer:

10(q-3)

last option

please brainliest me btw

Step-by-step explanation:

The expression states 10q-30

The GCF is 10 (30 GCF by 10 Is 10)

Factor out 10

After, divide all the terms by 10

10 (10q/10) - 30/10

Simplify this and we get

10(q-3)

so in conclusion, it is the last option.

NEED HELP PLEASE!

Answer:

$(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16$

Step-by-step explanation:

Complex numbers identity:

The complex numbers identity is:

$i^2 = -1$

Square of the sum:

$(x + y)^2 = x^2 + 2xy + y^2$

In this question:

$(x + (3+5i))^2$

$x^2 + 2x(3+5i) + (3+5i)^2$

$x^2 + 6x + 10xi + 9 + 30i + 25i^2$

$x^2 + 6x + 9 + (10x+30)i - 25$

$x^2 + 6x + (10x+30)i - 16$

$(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16$

If you drew a horizontal line on the coordinate plane, what could you say about the y-coordinate for every point on the line?

sattari [20]

It's the y intercept.
If y = a then every point on the line would be (x,a)
The lines slope is 0. I know that has nothing to do with the question, but it is true and it gives me 3 things to tell you.
