d=28g I might be wrong, but we can find this by dividing 140 by five, which equals 28.
For number one you do 15-9 which is 6 and that’s the answer
For number to do 25-18 which is 7 and that’s the answer for that one
Answer:
z=-y-11
Step-by-step explanation:
let's take out the parenthesis
-z-11=y
Now put 11 on the other side
-z=y+11
Then make z positive
z=-y-11

Explanation:
____________________
Given:
____________________________
-2(5a − 3b²) − 4b + 3 ;
_________________________________
"Use the distributive property [of multiplication] to expand the expression."
______________________________________________
Note the distributive property of multiplication:
______________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
______________________________________________
So, we have: " -2(5a − 3b²) − 4b + 3 " ;
______________________________________________
Start with: " -2(5a − 3b²) " ;
______________________________________________
-2(5a − 3b²) = (-2*5a) − (-2*3b²) = (-10a) − (-6b²)
= -10a + 6b²
________________________________________________
→ Now, bring down the rest of the problem;
________________________________________________
-10a + 6b² − 4b + 3 ; which is: Answer choice: [B].
