Answer:
7 19/20 = 7.95
Step-by-step explanation:
I assume you mean 4+6/5 + 2+3/4
Commutative property
4+2+6/5+3/4
Associative property
(4+2)+(6/5+3/4) = 6 + (6/5+3/4)
Multiply by 1
6/5*4/4 +3/4*5/5
24/20+15/20
39/20+6 = 6+1+19/20 = 7+19/20
-4 = ?
<u>Step 1: Substitute -1 for x</u>
7x^3 + 5x^2 - 2 = ?
7(-1)^3 + 5(-1)^2 - 2 = ?
7(-1) + 5(1) - 2 = ?
-7 + 5 - 2 = ?
Answer: -4 = ?
