Answer:
Step-by-step explanation:
4ab(a-b)+b(2b-2a^2)
=4*1*-1[1-(-1)]+(-1){2(-1)-2*1^2}
=-4(1+1)-1{-2-2}
=-4*2-1(-4)
=-8+4
=-4

the decimals are commas and the double decimal is a real decimal
Answer:
1 and 4/35
Step-by-step explanation:
Use distribution property to solve:
6/5 × -5/7 -3/4 -5/7 × 4/5 = -5/7 ( 6/5 - 3/4 ) x 4/5 = -5/7 ( 24/20 - 15/20 ) x 4/5 = -5/7 (-39/20) x 4/5 = 780 / 700 = 1 4/35
Answer:
f(-2) =3
Step-by-step explanation:
f(x) = 9+3x
Let x=-2
f(-2) = 9+3(-2)
= 9-6
= 3
The formula for the area of a rectangle is:

w = width
l = length
First, we have to convert 2

into an improper fraction, then into a number. The improper fraction would be

. Let's convert that into a decimal.

Let's multiply
