To remove the parentheses, you just distribute.
So, it will become 3ax + 3b^2 - 3c +2. I don't think there is any like term in this expression.
Answer:
x < 5
Step-by-step explanation:
Step 1: Simplify
7x−35<2x−10
Step 2: Substract 2x from both sides
7x−35−2x<2x−10−2x
5x−35<−10
Step 3: Add 35 to both sides
5x−35+35<−10+35
5x<25
Step 4: Divide by 5
5x/5 × 25/5
x < 5
Answer:
Step-by-step explanation:
number 2
Answer:
-46
Step-by-step explanation:
4 - 2(a^2 – b^2)^2 =
= 4 - 2(3^2 – 2^2)^2
= 4 - 2(9 - 4)^2
= 4 - 2(5)^2
= 4 - 2(25)
= 4 - 50
= -46
When
|a|=b
assume
a=b and -a=b
so
4+|7-m|=5
minus 4 from both sides
|7-m|=1
assume
7-m=1 and
-(7-m)=1
7-m=1
minus 7 both sidees
-m=-6
times -1 both sides
m=6
-(7-m)=1
distribute
-7+m=1
add 7 to both sides
m=8
m=6 and 8
