(2x² + 3)(4x +5) -8x(x²-2)

2x²(4x + 5) + 3(4x + 5) - 8x(x² - 2)

8x³ + 10x² + 12x + 15 - 8x³ - 2

= 8x³ - 8x³ = 0

= 10x² + 12x + 15 - 2

= 10x² + 12x + 13

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
