Answer 1

Answer:

4, 761

Step-by-step explanation:

5p²( 2p + 5q ) + 4p ( 3p - 2q )

p= 3, q=3

For instance 3w= 3x w, so that's what we are going to do for this question.

now let's solve the brackets

5 x 3 ² (2 x 3 + 5x 3) + 4x3 (3x3 - 2x3 )

according to BODMAS we solve the brackets first.

= 5 x 3 ² (6 + 15) + 4 x 3 (9 - 6)

= 5 x 3² (21) + 4 x 3 (3)

Now, we have solved the equations in the brackets, let's solve the one outside the brackets.

= 225 x 21 + 12 x 3

= 4, 761
