Answer:

(-3b) (10a -3b)

Step-by-step explanation:

(5a–3b)^2–25a^2

Replace (5a–3b) with x

x^2 - (5a) ^2

We have the difference of squares

( x-5a) (x+5a)

Now replace x with (5a -3b)

(5a -3b -5a) ( 5a -3b +5a)

Combine like terms

(-3b) (10a -3b)

Answer:

(5a-3b)²-25a²

= 25a²+9b²-2×5a×3b-25a { (a-b)²= a²+b²-2ab}

=9b²-30ab

=3b(3b-10a)

= -3b(10a-3b)

Can’t figure out number 10
Ivanshal [37]

Answer:

r = 15 1/6

Step-by-step explanation:

change every thing to have a 6 in the denominator

31/6 = 5 1/6

60/6 = 10

add the 31/6 to both sides to get the r by itself

60/6 + 31/6 = 91/6

r = 15 1/6
