#5 I'm having trouble doing that

timofeeve [1]

The distance formula is the square root of (X2 - X1)^2 + (y2 - y1)^2. Let D = y and c = x. Plug in the numbers now. Your equation is now the square root of ( -3 - (-5)) ^2 + (-2 - (-4))^2. Now complete it, your answer is 2.82...

Factor: 64v^4 - 225w^10

love history [14]

Answer:

( $8v^2-15w^5)(8v^2+15w^5)$

Step-by-step explanation:

STEP 1:

$8^{2}$ $v^{2*2}$ - $15^{2}$ $w^{2*5}$

STEP 2:

$8^{2}$ * $(v^{2})^{2}$ - $15^{2} * (w^{5})^{2}$

STEP 3:

$(8v^2)^2 - (15w^5)^2$

STEP 4:

( $8v^2-15w^5)(8v^2+15w^5)$

What numbers multiply to -756 but when added = 1

telo118 [61]

So?
-756*x +x =1 ?
-755 x = 1
x= -1/755

or
what two numbers when multiplied equal -756 but when added together equal 1?

numbers are x and y
x*y= -756
x+y=1

rearrange the 2nd eq
y=1-x
substitute

x(1-x)=-756
distribute
x-x^2=-756
solve for zero
x^2-x-756=0

factor/quadratic equation
