Sorry I am not sure but I think it’s the last one
Answer:
14(x + -3) [I'm not completely sure but I believe this is the answer]
Answer:
x = orgininal angle
3x +20 = supplementary angle
1. x + (3x+20) = 180
2. 4x + 20 = 180
3. 4x = 160
4. x = 40
The orginial angle is 40
The supplementary angle is 140
Step-by-step explanation:
1. define your varibles using the words given
2. add them together to equal 180, because they are supplmentary.
3. combine like terms.
4. subtract 20
5. divide by 4
6. you find x, now plug it back into your variables at the top:
x = 40
3(40) + 20 = 140
Answer:
Step-by-step explanation:
48 ÷ 9 = 5·33333333333 Reoccurring
So you will need 6 packets of to cover the ·3333333333
X^2 + 4x + 8 = 0
( x + 2 ) ( x + 2 ) = 0
